dns_name4(3) [debian man page]

dns_name4(3)						     Library Functions Manual						      dns_name4(3)

NAME

       dns_name4 - look up host name

SYNTAX

       #include <dns.h>

       int dns_name4(stralloc* out,const char* ip[4]);

DESCRIPTION

       dns_name4 looks up the domain name for the 4-byte IP address in ip. It puts the (first) domain name into out and returns 0. If the relevant
       in-addr.arpa domain does not exist in DNS, or has no PTR records, out will be empty.

       If dns_name4 has trouble with the DNS lookup or runs out of memory, it returns -1, setting errno appropriately. It may or  may  not  change
       out.

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.

DOMAIN NAME COMPRESSION AND CANONICALISATION

       The Net::DNS::Mailbox1035 and Net::DNS::Mailbox2535 subclass packages implement RFC1035 domain name compression and RFC2535
       canonicalisation.
