    Hello. i installed on my server csf firewall.
    After review security server.shows message error the Sections of warning .
    This indeed is a topologically error.
    Please if someone can help me to. How is this to repair and correct.
    Check nameservers

    Code:
    At least one of the configured nameservers:
    ns1.X***********
    ns2.X***********
    should be located in a topologically and geographically dispersed location on the Internet - See RFC 2182 (Section 3.1)

    Are your nameservers in the same /24 (aka Class C) IP range? That's probably the reason you're getting this.

    OK, a couple of things: You have 5 IP's on a dedicated server and your netmask is 255.255.255.0!?! Your provider didn't give you a subnet? OUCH!

    If you have IP addresses configured for your nameservers that are "neighbors" (ie: near each other in the same Class C) then you're going to get that message. It's not fatal, and won't cause your DNS to not work. But ideally you should have nameservers on DIFFERENT servers in DIFFERENT locations (datacenters). That's why you get the message.

    Hello. Yes you are right. Exactly Domain Name Server dns main one is! And I have a question. That if I change the dns server name or do I go up .. problem for sites not created yet?
    Because currently the dns to something else Rvydvmyn is dedicated. And if I now want to change. Tumultuous not you register?

    I do not think I understand what you are asking (I'm guessing you are using a translator of some sort).

    I think that there will not be a problem with your DNS servers actually working. It is the best idea to have separate nameservers from different providers. But if that is not possible, then you can get by just fine without.

    Hi,

    That is just a CSF warning to let you know that all IP address comes under same subnet. You may ignore that. That is not going to get you into any sort of troubles.
