hello every body,
i want to say that i read soooo much about the hiding the server and i still have a problem, can any one help me please
to be sure that i read enough, i will tell you some of what i can imagine, hop that you can tell me some thing, that help me to continue(where the design of the network is of three stages 1)public server 2)access node 3)protected server where it said that the public server not store any contant and can offerd as a servive by the ISP(is the public server work as proxy???))
what i understand is as follow:
the client connect let to say (www.amazon.com) so that URL is gose to the DNS to lead the client to the ip address (not of the true ip of amazon is that right if yes so how the DNS work because it must laed him to the public server and the public server check him and request a port no. and return that port no + the ip of the access node to the client in a redirection message the close the connection with the client) here the client now think that the access node is the true server and then the connection with the server is done through the access node
please i have a problem that what is stored in the DNS ???
and how it lead it to the public server at first????
note that there is many public servers and many access node, i think to continue even if one of them have an attack flood, so how the DNS know where to lead the client and there is an attack or the DNS not regard
and for multiple public server is the ip of them varied?? i think yes
that may be help little
It is recommend having more than one public server with different service providers. DNS should be offloaded to a third-party service that offers round robin load balancing with active failover functionality.
thank you in advance for any help, be sure i do my best in searching, with no enough information to help me, and i indeed need to know all that
doing any thing to me is very kind of you
best regards
