Hi

Using 5.8.8 and due to tight control of our software stacks I cannot make use of non-core Perl modules.

I'm looking for a reliable method of returning the FQDN from an IP but using gethostbyaddr() is not reliable as it'll query /etc/hosts first which matches short hostname and the FQDN returned maybe an alias.

I cannot use Net::Nslookup or Net::DNS and am loathed to call `nslookup` if I can make use of a nice neat Perl module that'll do what I want.

Am I resigned to a system call or can I force gethostbyaddr() to use BIND or another core module to return the FQDN?

Cheers
