Strange ping/DNS problem

I'm having a ping/DNS resolution issue with a new VPS that I can't wrap my head around. When I ping any invalid domain . . . it somehow resolves to the IP below. The hosts file is clean.

Anyone have any ideas?

ping fhieemfdafqqr.com
PING phx2-ss-5-lb.cnet.com (216.239.120.187) 56(84) bytes of data.
64 bytes from phx2-ss-5-lb.cnet.com (216.239.120.187): icmp_seq=1 ttl=243 time=83.2 ms

cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

dig fhieemfdafqqr.com
;; QUESTION SECTION:

    Sounds like when I get a 404 at home I just get a bunch of ads (because the $130/m isn't enough for my cable company). Maybe it's rerouting that dns on the host node for a little extra cash? What's a traceroute look like?

    Private tunnel time to your own resolvers. Fixes any messing around.

    You're missing some output from dig, namely the header. Can you provide that?

    add a search domain to /etc/resolv.conf

    Example:

    search d3vm.net
nameserver 10.10.10.101
nameserver 4.2.2.1
nameserver 4.2.2.2
nameserver 4.2.2.3
nameserver 4.2.2.4

    It's likley your search domain is set to "com" so when you ping a random non existant .com domain it's going to *.com.com.

    That was my thought, but this is a reputable provider, and I have another VPS with them at the DC that is not doing this.

    Traceroute is as expected.

    Interesting, I just wget'd fuyfdgadu.com and got this:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">


    Metasearch Search Engine - Search.com

    Well if you visit the IP that's what you see

    Yeah, that's what I'm thinking too now.

    I misunderstood. I thought this was an issue with your home ISP hijacking DNS.
