I'm running some small ISP here and I own couple of IP ranges.
I have given a few public IP addresses to some of my customer and they are running mail servers on them. They have demanded me to add reverse DNS entries (PTR
) for their IPs.
I have Bind running on my server. Can I add multiple PTR
records in same server/same file?
IP range I own: 192.168.10.0/24
Customer A: 192.168.10.103
Customer B: 192.168.10.199
Customer C: 192.168.10.169
Customer D: 192.168.10.69
Thanks.

As you can see from this TLDP example you can have multiple
PTR
records in the same zone.It is a good idea to put any IPs you allocate into your reverses file to avoid duplicates.
