Hello,
Indeed my question was on A record but the issue is on PTR record.
I can configure the following line:
_ptr.dekil.nl. 3600 IN PTR _81.99-129-109.adsl-dyn.isp.dekil.nl
It works....we can use "_" in both sides.
But what is strange is that the following configuration do not work:
9.10.238.195.in-addr.arpa. 3600 IN PTR por_tal-bis.skynet.be.
"_" is not allowed
Is it due to extra check by bind when it sees it is an arpa zone so no "_" is allowed?
Regards,
Carlos,

You are mixing the two things here. If the provider has asked you to create a PTR record, why do you keep trying to create a forward record? There’s some information missing somewhere.
