My hosting provider host DNS For all our sites, however, we are needing to point records to another DNS Server, to host DNS for some "Sub-Domains".
#1: (DNS On our hosting server)
A - sub.domain.com - 0.0.0.1 (Points to our in-house server's static IP
#2: (DNS In house)
Our router has DNS Port opened
Records in DNS Are created for the sub.domain.com
My question is this.
Right now, my in-house DNS is NOT being used, how can I make the world use my DNS for the sub-domain.com
