Bind DNS record


I have just started a new FC2 server at a new provider.
The IP assigned does not have any PTR record.

I tried to put one in my DNS zone in BIND but nothing happens.
Here is the entry in the zone file: IN NS

Still no PTR record detected for that address.

Should I contact the provider? Should they insert a PTR somewhere else in their network config?

The owner of the IP block has to set up reverse DNS. It's largely ignored these days, but some quirky things still need it. Hopefully they have control over the block, to find out who ARIN has assigned it to, you can whois your IP.

The above is a delegation record, not a PTR record. Your ISP would enter this on their name server to delegate the SOA for the PTR record towards your name server. Should your ISP actually delegate PTR record SOA's (most do not), then the reverse zone file (not forward) on your name server would have: IN PTR

BTW: As others have pointed out, ISP's do not "typically" delegate PTR records to a customers name servers. But most will make the PTR record change on their name servers. Same net effect, but you have to go through the ISP to make any PTR changes.

Thank you all.

I asked my Provider and he will add a record.
