At least two name servers (but no more than five) must be indicated and these must always be accessible on redundant paths. When a domain is first registered, DENIC checks whether at least one of the first three bytes of the IP address of at least one of the name servers differs from those of the others indicated."
yes, it is operational, and i ran the denic requirements past midphase support again tonight, and they told me they are 100% compliant.
i suspect that united-domains are playing any trick here. their price structure is a cheap domain, then when you want to alter the details, change a nameserver, etc, you pay the same price+ you paid for the registration of the domain!
like i said, united domains already had 2 stabs at changing this with the midphase details, and they already charged me for 'changing the nameserver' but have yet to do that. so is it a charge for each failed attempt? that could work out to be quite a lucrative business for them
i sent one more mail, so i will wait to see if they can finally do this or if they chose to refund. otherwise i complain to denic, already wasted enough of my time on this crappy company
