Hostnames live in domains defined by zone files. So when a hostname is
changed, a zone file has to be changed. Whether that's NSI's zone file
or someone else's doesn't matter: the zone has to be changed. If the
hostname is glue, at least two zones may have to be changed: the
actual zone enclosing the hostname and that zone's parent. Changing
glue in will have no impact on any glue that might or might not
exist in .com or any other zone outside the domain for that
matter. Well except possibly for the uk or root domains if your server
is listed in the NS records for or uk zones.

You will need to repeat that for every other registry/zone where the
old IP address of the renumbered server exists as glue. If the glue
isn't updated, the parent zone will be directing queries to the old IP
address which might not be there any more or not running a name server
for the delegated zone.
