We will soon be rolling out a new option for our commercial cable modem customer -- static IPs. As a member of the new product deployment group, I get to be one of the guinea pigs to beta test the product. So, tonight I brought home one of our SMC 8013s, a cable modem & router.
I was given config file to upload to the box. After doing so and connecting it in place of my Motorola SB4101, I was online with my new static IP. I have a /30 subnet, which gives me 1 IP for the WAN side, 1 for the LAN's gateway, and 2 for hosts. Not wanting to putz with my LAN's config just yet, I'm still using NAT.
Sometime next week my boss and I are going to swap modems to simulate a node move. Basically, we want to make sure that what's currently my modem will come online at his house with the same IP I'm getting here, and vice-versa for the modem he now has.
As an aside, I want to note that dyndns.org continues to give great DNS service. With a new public IP, I needed to update the "A" record for mail.building-tux.com. After logging into dyndns.org and changing the IP, the record propagated very quickly. I was able to send test emails to myself from my Gmail and Yahoo! Mail accounts within about 15 minutes.
