Both nameservers in the same subnet? Is it just the German DENIC which demands that the second NS has to be located in a different net or is that a global requirement? At least it is highly recommended.
Most registrars do not care. I even saw some that require you to provide two IP addresses on the web form, but you could simply type same IP address twice. After all, if all your name server(s) become unreachable, it is going to hurt only you. Once I saw an organization that had two DNS servers on separate networks. But the servers were located in the same rack, connected to the same UPS that was barely big enough to power them up for about a minute in case of power failure. Most registrars realize that people will do stupid things like that if they start really forcing policies, so they simply don't bother.
