NAME
  ipcheck - Dyndns.org client to register your dynamic IP address

SYNOPSIS
  ipcheck [options] Username Password Hostnames

DESCRIPTION
  ipcheck is a simple Python script to register your dynamic IP address using the NIC V2.0 protocol.
  It aim to be fully compliant with the dyndns client specification.

  The script is very easy to use and supports multiple methods for determining the external IP (parsing
  interfaces on the local machine, web based IP detection, direct support for devices from Linksys,
  Netgear, Draytek, Netopia, HawkingTech, Watchgard, Cayman, Nexland, ZyXEL, SMC, Compex, UgatePlus,
  DLink and Cisco).

  Run the script with no command line arguments for quick start instructions.

  Example 1: the external IP is on eth0 of the current machine:

    # ipcheck -l -i eth0 username password hostnames

  Example 2: you are using the Linksys routing device:

    # ipcheck -l -L linksyspassword username password hostnames

  Example 3: you want to use web based ip detection:
