To echo RohanRNS’s comments, go to DynDNS.org. The “Dynamic DNS” service is free for up to five locations. They also offer some neat services for circumventing ISP port e-mail blocks. Actually, they offer several really useful services for much less than typical vendors.
If you use a DSL/Cable router, it may already support the Dynamic DNS service. Otherwise, you need a potentially free software client on your home system to report the current IP address to DynDNS. It’s all explained on their web site (www.DynDNS.org
). I use several Linksys routers that support DynDNS.org, but I have read that their popular wireless “G” router no longer does.
If you use the free service and like it, think about paying for the “Account Upgrade” (US$9.95/yr) to help support the organization. Also, be sure to read about the organization’s history at the web site.
