dns reverse lookup on co-lo address space

[noc-ops]

Hi,

[Apologies to those of you who received this e-mail in multiple
forums.]

Say if I have a domain name called domain.com which resolves
to 192.168.0.0/24. Now if I decide to move my server farm (collection
of 10 machines) to a co-lo's network (172.16.0.0/24), what do I need to
do in order to resolve reverse lookup for these machines to my
domain.com.

Would I need to ping my registrar on this? If so, any insight (BCP)
will be appreciated.



regards,
