why would you want to change your windows dns settings?

[keakar]

There is no such thing as "DNS throttling". Queries aren't send on every single packet, once it's done it's cached for a while by the OS. Also, no packets pass thru the DNS, so it can't throttle your connection.

ok, I guess im just not fully understanding the actual process but its not important as long as im sticking with the default 250 queries im doing it right.

the end results I am seeing are so wildly different each time, that im not sure which of these results can be trusted.

different times of the day you get different lists and I understand this is because of usage habits when people get off of work vs being at work but beyond that, I can run two test 10 minutes apart and get a 20% or more change in the order and speeds of dns servers listed and where they are on the list.

because of this im not sure how to formulate a choice to pick as better or worse then my default dns.

do I just do a handful of tests each hour or couple of hours and average it all out?

and if im only looking at say a 10% or less difference, is it worth changing dns just for that small change? or is that not as small a change as I am thinking it is?

Use 8.8.8.8 as primary, 8.8.4.4 as secondary. Those are the Google ones.
If issues persist then keep posting, doing pings, traces etc as the issue is probably on another part of the connection (which I'm fairly confident it is).

 

[keakar]

well I suspect its the regional lines being worked on or something because its like one or two websites go out for a few minutes and then it can connect again, almost like somewhere between me and a central hub or something there is temporarily downed connection which then comes back on again.

this morning it was TPU and SUBSIM and subsim is in texas so I suspect im losing certain "sections" of networks momentarily on occasion but its like only for a minute or two and not every day. some days it happens two or three times and sometimes its fine for a week without an issue. I regularly use around 6-8 websites every day so this is where I notice things having "hiccups" in connecting.

these connection problems are more of a side note and not my main concern or why im looking into the dns thing, im doing it because I was told I can be faster going to a dns I select rather then letting my ISP do it for me.

while learning about this I was just wondering if switching dns might also be an "accidental" cure for these hiccups im seeing, so I asked about this. these hiccups requiring a second click started about a year ago but recently got worse about a few weeks ago when my ISP started upgrading servers and doing system maint on the lines so when something fails to connect now it takes like a full minute or two before it connects when clicked.

Nodes get saturated sometimes, or peering issues may start at certain times of the day. The "second click" needed to open a link can derive from other issues (ranging from DNS to malware) .

Do the following steps please:

1) Download WinMTR http://sourceforge.net/projects/winmtr/files/WinMTR-v092.zip/download
2) Open it, go to options and put 1.0 sec as interval.
3) While you're having issues with TPU, type " www.techpowerup.com " on host and click start.
4) Leave it running for 500-1000 packets.
5) Click the "Copy text to clipboard" button and paste it here.

This is basically a tracert but with some extra features and more than 3 packets. Helps to identify where the issue may be and then we can try to fix it

ok, will do. I just hope it happens again soon, its like showing a mechanic an engine noise, as soon as you try to recreate it on purpose it doesnt want to act up again lol.

I don't think its computer related since I think the other computers get this issue as well but its hard to say since they don't go to the same websites that I do but they have said now and then they cant connect to a website they are trying to reach

now the setup I have is a cable modem with router then 3 computers running off of the router

so do I change the router to increase speeds or is the gateway really through the modem?

I read something somewhere on a Q&A list that suggested the modem had to be looked at as the gateway but I couldn't follow or understand the brief comments about it much

I found that the DNS for Charter would many times be unresponsive, or just plain couldn't be found. Changed the dns to the OpenDNS address and things have been flawless.

Just a FYI they have been testing cached DNS proxying/hijacking, where you may resolve a page served up by Charters DNS servers if they see the DNS response and don't like it, I have seen this twice and it seems to be at the main hub that its happening.

http://www.dslreports.com/forum/r17871432-Charter-Corrupting-DNS-protocol-ie-hijacking-hosts-

I had to call and go through two layers of shit to get them to exclude my IP, so now I actually return accurate results.

The "No Response from Host" and some of the "packet loss" is just ICMP not being enabled on certain hops and some mitigation, nothing weird. While you did this MTR you had this issue? Because I can see a huge variance on latency (56-340 with 161 avg) but 0% packet loss... only compare the 530/530 you sent/recv from your ip against the 536/536 sent/recv from Yahoo.

If there was an issue browsing during this MTR then I'd point the issue to malware/spyware.

 

[keakar]

well it was hanging up for the first minute then it would half load the page during the second minute but around the 3 minute mark it was working ok

it wasn't a very good test, but it is on par for the kind stuff im running into

I just assume its the servers on the other end holding things up, not my connections but then I don't know anything about all this network stuff so I guess anything is possible

 

[Daemmon]

Packets send/received are working flawlessly. Your ISP/Modem/Router/DNS/Hops... everything works correctly on that trace.

Run some adw/malw cleaner, adwcleaner and/or malwarebytes are what I'd normally recommend.
Also, check for plugins/extensions on your browser, specially if you're using Chrome.

If you find anything that you can't repair/remove I'd suggest google+posting on specific forums for spyware/malware issues. There are several known ones that will be very helpful. Specially with more advanced tools.

PS: Spikes can be somewhat common, and 340ms highest packets are not good, but not enough to drop an established connection and make a webpage to half load / not load correctly.

every day before I shut the computer off I always run:
superantispyware
registry cleaner - to clean registry and remove any browser objects (which I remove all) or startup ad-ons (of which I only leave avast on that list)
malwarebytes
internet options - to clean browser history
windows disk cleanup
ccleaner

so its not that im not cleaning things up

this morning it just did it for tacomaworld.com so I ran the test and this is the result:

hope this helps confirm whats going on

 

[Daemmon]

Both burgerking.com and bk.com have ICMP disabled, so those won't be of much help.

But on the first one:

| 10.0.1.5 -------------------------------------------- 3 | 648 | 635 | 10 | 67 | 359 | 13 |

Do you have any idea what this IP is?

Router? Modem? First hop outside your local connection? That's where all he problem starts with the spikes and 3% packet lost.

I have no idea what 10.0.1.5 is at all but i'll google it and see what comes up.

ok its America/Los_Angeles (UTC-8) and this is all I see about it: https://db-ip.com/10.0.1.5

I also see some stuff mentioning "cloud" in reference to this number

 

[R-T-B]

It's a private address. Googling it won't be of any use, as it's likely specific to your setup or ISP.

 

[Daemmon]

Yeah, it's most likely a local LAN component or one of the first hops on your ISP.

 

[keakar]

so this delay to connect stuff all looks like outside delays along the pathways and nothing to do with my settings or anything in my control then huh?

 

[Daemmon]

It really depends what that IP is. If it's a router or your modem or anything like that then it's something probably on your side and you may be able to fix it.

If it's one of your ISPs first hops then you should call your ISP, tell your issue and forward this MTRs to them so that they can see what the issue is.

If it's one of your ISPs first hops then you should call your ISP, tell your issue and forward this MTRs to them so that they can see what the issue is.

well that IP is nothing on my end but I cant speak for my ISP, I can say that is not the number my router or modem use

as I mentioned earlier in the post, I have a cable modem then a router which feeds 3 computers, 2 hard wired and one wirelessly

another key thing to point out is when these things happen its NOT my connection to the internet, its certain sites I am trying to connect to when I am on the internet, that dont respond and give me the white screen saying "unable to connect blah blah blah" so its often just one or maybe two sites may not be responding for a minute or two or sometimes 5-10 minutes and while they mat not work, if I try 3 or 4 other links to different websites, they will be working fine and instantly connect

ok, I will try to ask this question one final time. I asked several times and it was never answered. (most likely because my posts are so long and ask several questions)

I have a cable modem with a separate router and there are three computers connected to this router, so ... where do I want to go to change the dns for all of them at once? router? modem? every single separate computer?

 

[Ahhzz]

you can't really change for all of them at once. The cable modem gets its dns from the ISP. The router's DNS is likely set to pull from the Modem, but you could manually set it to something else. The PCs most likely look to the router for their DNS, so changing the router, would likely change the PCs.

ok so then there is really no way for me to truly change my dns for better speeds then, since the modem is the core gateway and it will always do what it wants to do and use its dns connection no matter what and I cant change that, or am I thinking about how this dns setting thing works in the wrong way?

if you set your computer a static DNS, it won't use the one from your ISP, as you computer will ask (example) 8.8.8.8 to resolve. The only thing, is that you need your internal IP + gateway (router) and the Router will use his IP, then will route traffic to the gateway and will ask to get an answer from 8.8.8.8 to resolve.

could you do a http://www.pingtest.net/ to test your ISP?

I verified all of these are working.
http://techpowerup.com = http://108.61.10.5
http://mail.yahoo.com = http://98.139.21.169
http://google.com = http://216.58.216.78
http://walmart.com = http://161.170.248.20
http://ebay.com = http://66.135.216.190
http://amazon.com = http://176.32.98.166

Note that WWW can direct to a different IP than non-WWW. A lot of these sites redirect to their WWW subdomain.

Just for info, some people might not know aswell, there is also Geolocalisation. Traffic will be routed to the closest server for some company. Like google, on my side, google.com will resolve to 173.194.123.0 , 1,2,3,4,5,6,7,8,9,14

cmd line: nslookup domainname , will give you all IP it will answer from. but like I said, some will have the same as other people ,but like google, you might not have the same. I think also microsoft is similar

https://www.grc.com/dns/benchmark.htm is also a nice tool for DNS benchmark.


Personally, I used my Videotron DNS but for kid computer, I put openDNS with filtering. I did the same for a customer. At work, we use google DNS for our iDRAC or any oter remote management that doesn't need local resolve

Router. You probably have no access to modem config, and even if you had you normally can't change that much.

Router DNS configuration will override the ISP ones on most scenarios. If you don't know how to do it, post Brand/Model (of Router) and I'll look into it.

I just went and set each individual computer to use open dns and so I don't need to mess with the router now. I did a week long test day and night one two different computers side by side and open dns always connected with no issues while auto detect ISP dns couldn't or had random issues.

I knew switching to open dns would stop my connection issues, but I just wanted to figure out and understand what was going on with the connection I had with auto detect through the ISP and I still don't know that.

im left to just "assume" that the ISP are sending me through a slow heavily overpopulated dns server (because its the cheapest to use) and that was the whole issue.

I want to thank everyone for helping me, I learned a lot here and still don't know a lot, but I know more about things I don't know about, if that makes any sense, lol.

Have you tested doing a nslookup to check what is the DNS resolving domains? Just go into cmd and type "nslookup" it will tell you what DNS is active and resolving currently.

If DNS are set to "automatic" on the router then probably the PC ones are being used, else it's probably using the ones configured on the router.
