Andover, KS | Static IP
I am interested in getting a static ip. I was looking through the Options for home and there are none with static ips. Is that something you can ask for, or is there some secret to getting one? |

| You can't get "A" static IP from AT&T. The smallest number you can order is a block of five addresses. This results from the rules used by most networks, where IP addresses with the least significant three bits all zero are used only to identify subnets, and those with the same bits all one serve as "broadcast" addresses whose messages get response from all other members of the subnet. AT&T uses an additional convention: the address with the low bits set to 110 in binary are used as the subnet gateway to the next level up. That leaves five addresses unassigned, and those are what you get in the package.
If you're confused by all the mention of "subnets" in that description, note that the static IP package forms its own little network on the larger AT&T network, so it's a subnet. Because of the conventions just described, the block size for such a subnet has to be a power of two. While you could have a 4-IP subnet that would give you ONE usable address, that would in effect waste 3/4 of the address space. AT&T apparently opted to use 8-IP subnets as a reasonable compromise for small business.
I happen to have such a package myself, and have had for the past six years. It's costly, but meets my needs since I run a data recovery service on-line and have to maintain a private FTP server for customers to upload their damaged files for repair. This requires a fixed address. When I first got it, I had to go through the "business" folk rather than the residential crew, even though the phone line was residential rather than business.
Not too long ago I was browsing through their web pages and came across listings for residential 5-static packages. One will cost you about $80/month in most areas, for 6-megabit sync. It doesn't get much cheaper at lower speeds. You also have to pay a $250 installation charge and use a special router. Are you sure you want to go this route?

I have my own server, with email and web services. I am using the DynDNS service to provide a domain name, but I was considering using my own domain(s). For this to work, I would need a static, as far as I can tell. My router is equipped to a handle static ip. I can set up a subnet, as well as any additional settings that may need to be configured. I don't want to pay a fortune for something that is basically a hobby for me. So unless something different presents itself, I am sticking with dynamic. 
Thanks!

You can use a custom domain name with DynDNS on a dynamic IP: »www.dyndns.com/services/dns/custom/. It costs more than using one of DynDNS's domain names - $27.50/year and of course you have the domain name registration fee which DynDNS can also do if you wish.
Your router might not be able to update a custom domain name (some can't) so check that before you jump into it. |

d_l: I just checked out the custom dns and that is a great service. If I could figure out how to get reverse dns to work with it, it would be perfect. I doubt that sbc would be willing to put in a ptr record for me.
Thanks for the info.

Can only get a PTR record if you have static service. Have you called AT&T and asked about getting static service? |
