How can you set up a server with a Comcast account if your IP address is not static and therefore subject to change without notice?
While I have dhcp, the assigned address stays the same for so long, it might as well be static. Also, while my address may change, my host name won't, as it's based on my mac address. So any host name look up will return the correct ip.
Say what?
Maybe in your own (windows) network but not from outside.
You need something like www.dyndns.org for reliable access on a dynamic ip. Host name means didly-squat.
I mean exactly what I said. My host name is derived from my mac address. I can do a host lookup from elsewhere and find my home IP. I rely on this for my vpn from my notebook to my home network. In the configuration for the vpn on the notebook end, I specify my host name as assigned by Rogers. I can even use the host command on another ISP, which returns my IP address. So, as I said, even though my IP may be dhcp, the host name is static and can be used to reach my home system. The hostname follows the form of "CPE<computer mac>-CM<modem mac>.cpe.net.cable.rogers.com". Since neither the computer nor cable modem macs change, the host name is permanent.
I see what you mean now. dig CPE00055dfefce4-CM014150004408.cpe.net.cable.rogers.com yields your IP... But still, why would you want to carry around that big mess when you could go to dyndns.org and get a nice short name? -- _____________________________________ John Andersen
