The new TZO DDNS perl client has an included daemon that will detect IP Address changes automatically at a user specified interval, anywhere form 1 minute to two days! Also, the daemon can detect IP Address changes of a gateway/firewall device like the Linksys Cable/DSL Router not just the local adaptor! With TZO DDNS Services you can run your own web server, email server, ftp server, chat server, shoutcast server, etc.
