#!/bin/bash
# info: add system ip address
# options: IP MASK [INTERFACE] [USER] [IP_STATUS] [IP_NAME] [NAT_IP]
#
# The function adds ip address into a system. It also creates rc scripts. You
# can specify ip name which will be used as root domain for temporary aliases.
# For example, if you set a1.myhosting.com as name, each new domain created on
# this  ip will automaticaly receive alias $domain.a1.myhosting.com. Of course
# you must have wildcard record *.a1.myhosting.com pointed to ip. This feature 
# is very handy when customer wants to test domain before dns migration.
