Blocking Site Finder at the DNS library level

It may seem like a strange update to the DNS libraries available, to make DNS requests return NXDOMAIN when they get the Site Finder IP address. But I feel this would be an excellent solution, even for technical reasons.

 

  1. All requests that used to return NXDOMAIN now return 64.94.110.11. Therefore, 64.94.110.11 can be considered to be the new NXDOMAIN.
  2. We do not consider the wildcard-resolved domains to be truly valid, even though they return 64.94.110.11.

Please note that the NXDOMAIN IP is different from that returned by sitefinder.verisign.com, because they don't want to have a message saying "we couldn't find sitefinder.verisign.com". There's a much easier way of fixing this, of course, but let's not put it past them.

Sure, it's inconsistent. But it's vicious and effective.

[new] hacking the DNS libraries (#1)

I may add this feature to adns if I feel like it sometime. I have to learn ADNS for a project I'm working on anyway.

I don't think anyone will have much luck making such a change to glibc, as that wouldn't be standards-friendly. Just the objection I sought to get around here. :(

Am I just being crazy here? Should I go off and scream at VeriSign, as suggested by many others, instead?
