Default DNS: bug or feature

Code:
$ echo "look up site ip-address"
$ nslookup sub.domain.tld
Address: 192.168.0.1

Code:
$ echo "then look up domains"
$ nslookup 192.168.0.1
192.168.0.1.in-addr.arpa name = domain1.com.
192.168.0.1.in-addr.arpa name = domain2.com.
192.168.0.1.in-addr.arpa name = domain3.com.
192.168.0.1.in-addr.arpa name = domain4.com.

Yes, thats the way ISPConfig adds PTR records.

But it's insecure, isn't it
I think that IP-address may have only one PTR record.

Its not really insecure because dns servers are laways there to be queried. But I agree with you that its better to change this behaviour so that only one domain is set in the PTR.

I will add this to the bugtracker.

In ISPConfig-2.2.22 it was fixed
- Bugfix: Bugfix for PTR records: only one PTR record per IP address; PTR zones are now created correctly
