DNS Optimization

A discussion on the MHV LUG mailing list pointed to the Gibson Research DNSBench utility. Letting it chew on all the nameservers it can find, then mulling over the results for a bit, produced this short list:

  • NY Public Library: 68.88.88.2
  • Level 3 Comm: 4.2.2.3 or .5
  • Yale: 130.132.1.10 or 11
  • NTT: 129.250.48.98

Feed those into Network Manager (or /etc/resolv.conf) in some permuted order and away you go… at least if you’re near Poughkeepsie and using Optimum Online. Change anything and the results will differ.

I’d been using OpenDNS at 208.67.22[02].22[02], but the new ones test out as marginally faster and are certainly more diverse. Who knew NYPL ran a DNS?
