Best Practise Reverse DNS Configuration for Subnetted Environment

-

hi,

i believe it's best practise add reverse dns lookup zone every subnet since there no way define size of subnet when creating reverse lookup zone left wondering point , why shouldn't create single zone entire environment?  i can see 3 possible ways create zone; either:

  • create single 10.in-addr-.arpa zone, cover subnets
  • since windows server doesn't ask subnet mask doesn't care how given address has been subnetted, me logical solution
  • create zones 10.1.in-addr.arpa, 10.2... 10.3... 10.4... , on
  • this reflect zones exist in ad sites & services
  • create zones 10.1.1.in-addr.arpa, 10.1.2... 10.1.3... 10.1.4... , on
  • this reflect how subnets being used in environment

what best approach, or down how 1 manage dns?

regards,

robert

i create reverse lookup zones possible private ips. unless have requirement exclude ranges registering, not see need proceed differently.
