NAME
	dgd_ip_number

SYNOPSIS
	string dgd_ip_number(obj)

DESCRIPTION
	The IP number of the connection associated with the argument
	`obj' is returned.

	This function differs from connection_name() in that the IP
	address is always returned, regardless of whether a reverse
	hostname mapping could be found.

	The caller of this function must either be a wizard or own the
	connection in question.
