This question comes from a conversation that a few coworkers and I had. When using active directory integrated DNS should you have a reverse lookup zone created for each subnet that is in AD sites and services.
We have just acquired another company and they have many more subnets in AD sites and services than they do in their reverse lookup zones in DNS. I think there should be a reverse lookup for every subnet that is in use. I have seen some websites that say a reverse lookup is not 100% necessary.
Does anyone have any info either backing up this opinion or disputing it. I am looking for what others are doing.
