Huh?  You mean they're not running their own DNS servers?  If they're not
running their own DNS servers but are doing hosting, they deserve what
they get.  If they are, they need to simply update their host object in
whois for their DNS servers.  (This may or may not work with "alternate
registries".)  Then, they can write a simple script to go through the zone
files they have and change the first three octets to the new address
