Such declarations seem silly, as they never change, but it is good style to declare constants in one section with mnemonic names, and not hard code them elsewhere.

The only thing that gets tricky in DNS is when 2 nets are on one reverse domain, when subnetting not modulo 256. Similarly, sometimes a.b.c.d is defined on the c.d domain server, as there is no b.c.d name server.

I always did it by hand!

NAME
Net::DNS::Mailbox - DNS mailbox representation SYNOPSIS
use Net::DNS::Mailbox; $mailbox = new Net::DNS::Mailbox('user@example.com'); $address = $mailbox->address; DESCRIPTION
The Net::DNS::Mailbox module implements a subclass of DNS domain name objects representing the DNS coded form of RFC822 mailbox address. METHODS
new $mailbox = new Net::DNS::Mailbox('John.Doe@example.com'); $mailbox = new Net::DNS::Mailbox('John Doe <j.doe@example.com>'); Creates a mailbox object which represents the DNS domain encoded form of the mail address specified by the character string argument. The argument string consists of printable characters from the 7-bit ASCII repertoire. address $address = $mailbox->address; Returns a character string containing the RFC822 mailbox address corresponding to the encoded domain name representation described in RFC1035 section 8.
