    Question Hide your ip in NSLOOKUP

    Hi,

    i am new here and also don't have a lot of knowledge about dns. So here we go.

    I got 3 servers. 1 is my mail server, with Exchange 2010. The second one is my blackberry enterprise server. The third one is my PGP server. Now it's called symantec encryption management server. All are working fine so that's not the problem.

    What i want to know, when i use nslookup, and type:

    nslookup mydomain.com

    It shows my ip address of one of the servers.

    I searched on google and it sounds it is not possible. Untill i tried some other domain's with the same setup as min ( keyserver,bes server,mail server ) and it didnt show me an ip address when using nslookup. Only the name of the domain.

    These are the examples: pgp.li and luxberry.cc

    nslookup pgp.li

    Name: pgp.li

    nslookup luxberry.cc

    Name: luxberry.cc

    Does anybody knows how to do this?

    It has to resolve to an IP for you to connect. If you saw a name instead of an IP, it was a CNAME. If you follow that chain it will eventually end with an IP address.

    Hiding your IP means nobody can connect to you. Computers can't connect to another computer by name. The entire purpose of DNS is resolving your name into an IP address so the computers can connect.

    You have to remove the ip from your dns zone
    but if you do that your domain will no longer resolve not sure if that is what you trying to achieve or not

    DNS is important

    The IP Address resolving is only an issue if it is internal. if it is a service which needs accessing then you either need a DNS entry, or you need to stick to connecting via IP.

    You could configure the server so that even though the DNS record points to it, only connections from a specific IP address are allowed.

    but as clouvider highlights.. It depends what you are trying to achieve.
