Verizon's DNS servers now helpfully remap DNS queries for some types of nonexistent domains to a helper page: vznassist.infospace.com. That's great, except for a few small problems, like breaking the internet. It looks like they haven't rolled it out to all customers yet, since my friends on FIOS still have normal DNS. For the meantime, I've switched to Level 3's (anycast) servers: 18.104.22.168 and 22.214.171.124, which still return the proper NXDOMAIN response. :-/
