If your IP never changes, why bother with it at all. Just memorize your IP address or pay a couple of buck to register a domain name that points to your IP.
Recommended Dynamic DNS provider?

I guess the issue is that the IP address, stable as it may be, is dynamically assigned by my provider and does not belong to me.
My understanding of domain registration is that you must assign the domain name to an IP address you own (i.e. 'rent'). I may be wrong but I doubt my ISP (Videotron) would agree to have my domain name attached to their (dynamically allocated) IP address.
I was thinking along the same lines, if it never changes why bother with dydns. I used to use TZO, actually still have it paid through the end of this year. It was configured on my router to update if it changes but it rarely does (only if I hard reset the cable modem). If you register a domain at godaddy you can use their DNS servers and just forward a web address to any IP address.
For example, I went to the command prompt and typed ping google.com and it came back with the IP 66.249.91.104
so going to internet explorer I type in http://66.249.91.104/ and it pulls up google's site. I could set up my domain to forward to google if I felt so inclined. In my case I realized that WHS has a built in dynamic dns if you create a windows live ID so I just have my godaddy domain forward to that, but otherwise I would probably just set up a script that emailed me if my IP address ever changed and then I would manually go in the one or two times a year it may switch to change it.

If you are using DHCP, you CANNOT say "my address NEVER changes". Just because it hasn't changed so far, doesn't mean it won't in the future.
Unless you have a static IP provided by your ISP (probably charging you extra for it), you have to assume that your IP COULD change at any time.
If your IP address changes very rarely, you may not need a DynDNS service, but that is a choice/risk you have to make.

I've just learned that my ISP ties the assigned IP address to the cable-modem's MAC address. So my IP address should remain unchanged unless I replace the cable-modem.
A colleague of mine had used GoDaddy to register a domain name that he pointed to his web-site hosted by Google. He received an email from Google requesting confirmation of the arrangement. So, for all of you folks who use GoDaddy, do they care what IP address you point your domain name to?

If your IP is tied to your Modem's MAC then you effectively have a static address. If you aren't trying to run a comercial site, I would just forget about any domain name and just remember the address. I have a static address at my office and I just remember it like I would a phone number.

In the midwest my ISP modem does a xxx request. This request is based on the MAC address of the modem. The IP given is just what comes from the ISP via DHCP for residential. You can reset your modem and typically get the same IP information by default. The package it recieves from the ISP is the configuration file from the ISP (lots of interesting info - much like a Cisco router configuration with service types, qos, DHCP etc). Sometimes a firmware update of the OS of your modem. The typical configuration file is an encrypted CM (configuration modem) file. To read some more have a look here:

You're a better man than I, Lou Apo!
I've committed a lot of things to memory but my cable modem's IP address ... not gonna happen.
While the DHCP server usually assigns you the same IP, it can change when there is a major power outage and you are down for a while, and other people come online before you do.
I would just set up a domain and point it to the IP. I have been doing it for years, there is nothing wrong with doing that.

Yewwwww can dooooooo it.
Its 12 numbers (at most), mine is 11. Make a little song or something.I don't know what you mean by the MAC address being tied to the IP. If that means an IP is assigned to each modem, then what you got is static IP. I think in general the way the ISP logs you on as a paid subscriber is by the MAC on your modem since there are no login names or passwords (as used to be the case with ppoe). Otherwise anyone with cable could just plug a modem in and get internet. Once they see the registered MAC address they kick out an IP via the DHCP server. DHCP servers typically default to assinging the same address to the same MAC provided it is still available. DCHP servers can be set up to hold an IP address for different amounts of time before releasing it to other MAC's. Perhaps your ISP has set that to a relatively long period or perhaps the physical network your ISP's DHCP router serves is small and the same people are continuosly logged in so that IP addresses rarely get reassigned.
