s/register/lookup/

it's likely that more domains go through the grist-mill of

I noticed yesterday that Register.com's (some of register's) customer
domain-hosting ips (dnsXXX.Z.register.com) were routing via prolexic's
infrastructure in FLA... Perhaps the plan was to migrate things over
to prolexic, deal with the 'attack' and then service real customer
requests from there?
