Recommended Dynamic DNS provider?

I don't know what you mean by the MAC address being tied to the IP

When you buy a modem that hasn't been registered to your ISP you can boot it up and see what happens. You will get an ISP provided web page telling you that you haven't registered the modem yet. You do get a dynamically assigned IP address from ISP though for a generically non assigned mac address. You will not be able to use the BB service that your ISP provides to you until your MAC address is registered. Its an interesting process. You can watch it with a network sniffer by passing your firewall with a direct connect to your external WAN network interface.

IE - I'm having the same issue of trying to reply again....

There are another couple of paragraphs but I can't post them for some reason....

When you register the MAC address with same said web page then the next time you boot your modem it goes to the same XXXP server. It looks up your MAC address the checks to see if you modem needs a firmware update (depending on what DOCSIS its able to run) and updates firmware based on MAC/Model of modem. It then reboots again using the same MAC address and downloads an encrypted configuration file telling modem what your set up will be including whether you have a static or dynamic address, tier of service, blocking of ports etc.

It seems related to the word

I'm on Videotron as well and I have dynamic IP from my provider (DHCP). My IP address rarely change but regardless it sometime change. My router (Sonicwall) is pretty good at keeping my DynDnS account alive.. but I wanted more..

I already have a domain of my own and It's hosted at GoDaddy. I wanted to use my domain name on my Videotron (ISP) dynamic IP so I purchased custom DNS services from DynDNS (aprox $30 if a recall properly) and made Dyndns manage my Domain DNS pointing the web and email to GoDaddy and my home address to my home IP.

Also I believe as soon as you pay any kind of service from Dyndns your no longer a free service thus no longer require to log every 30 days.

This being said I love my current set-up as it's clean and fairly cheap. Using my home.Mydomain.com to get to my home system and www.mydomain.com for my web site. I can run a Web server, mail server or anything else from my home dynamic IP as long as it's not generating to much traffic as it's against the user agreement of my ISP.

Hope this information can be somewhat helpful.

Suddenly the idea of using a CNAME record seems much, much easier. Going to your ISP's website will state if you have a dynamic or static IP. Typically cable is static or semi-static (there are scenerios that can cause it to change), DSL/FIOS and dialup are dynamic.

home.mydomain.com (CNAME) -> myact.dynamicdnsprovider.com (A) -> semi-static|dynamic IP

The CNAME record will be cached by DNS clients and will not have any performance impact. As most dynamic dns providers are free.... it seems easy enough to run a background service to "keep alive" the account. No issues with ocassional changing IP addresses. Pointing your domain/subdomain directly to a semi-static IP is asking for headaches IMO.

Some ISPs will allow you to purchase a true static IP for an additional monthly fee. My current ISP is retarded and won't let me purchase just one - I have to get them in blocks of 12. If you are doing advanced networking (or have roommates) this can be worth it - you can setup each computer with two IP addresses, one public and one private. This can be a huge benifit to any P2P programs you may have, and dramatically reduce the firewall/port forwarding headaches you may encouter (as there is no NAT - Network Address Translation - for any computer that has a direct external IP).

Speak of the devil! I just got an email from no-ip which monitors my home cable modem. It is dynamic but it hasn't changed in two months and they were going to boot me off. I also use dyndns as a redundant service for my home IP but they haven't sent me any emails about kicking me off.

If you are using the free service then just logging into the service will authenticate your use. I use both and paid for noip dot com. I use no ip dot com for two different dynamic addresses. Works for me.
