[netopia] Static IP changing to dynamic: HELP

Several years ago I got great help here setting up a pinhole in our 3346.
Now the situation is changing because to get higher performance,
ATT says we need to go to dynamic IP addressing.
The story is here:

On our library website:

»banderalibrary.org

we have a link to allow our users to access the library catalog. (It is
on the first page in the middle near the bottom.) This link is to a fixed IP address
(70.128.153.246 on the link) and works through a pinhole in the Netopia modem/router
that is set up to access the server with the catalog on it.
That has been working fine for several years now but won't work with dynamic IP addressing.
Can we set up a subdomain name like this:

»banderalibrary.org/catalog

to do the same thing? If so how do I do it?

Someone here know?...or at least point me in a the right direction.

Thanks for any help

What is changing with your dsl, what do you have now what are you changing to

When I lookup the name
banderalibrary.org

I get this ip address
66.96.133.14

You can use a service like dynamic dns or no-ip to get a domain name that points to your current public ip address

Thank you for your reply!

We will change from our current DSL to the fiber-optic
based Uverse service to get better performance for our
public-use computers. But apparently it has to employ
dynamic IP addressing.

How did you get that different IP address? As you
can see if you hover over the "Online Library Catalog" link
on our website, the IP address is as I stated. And
clicking through gives this URL:

»70.128.153.246/cataloging/servle···y+Search

I just checked it a minute ago because I wondered if ATT
had changed it in the process of our upgrade.

Also, if from within the library I enter this URL:

»www.whatismyip.com

I always get the same IP address: 70.128.153.246.

Anyway, I will look into "dynamic dns" and "no-ip"
services and try to see if and how that would solve
the problem.

Thanks again for the leads!

There are two types of "uverse internet" while both types employ dynamic public ip's
att rarely changes the public ip with the uverse internet service

I used a "whois" lookup on banderalibrary.org

I've also done a "whois" on the public ip you posted and it looks like you have a block of public ip's
att can sell you a block of public ip's with the uverse internet the ip's will most likley change

Sounds like you know a lot more about ATT than our ATT salesman.

Will dynamic IP addresses change once the modem is logged in? The reason I ask is we leave the system on all the time so our WiFi is available as a hotspot all the time (near the library.) If it only changes when the modem is powered down then back up at a new logon, I can set up the new IP address on the website on those occasions and I don't have to worry about this dynamic address issue.
Thanks for the help and pointers!

Oh, I resolved the IP address issue. The 66... address is for Dot5Hosting (host for our website.) Our library DSL IP is as I
stated. And that is problem with a dynamic IP address. If that changes randomly our users can't get to the online catalog.

just use a dynamic dns service, there are several out there, to point to your catalog. then set you link on the web page to point to the page name. say you name it banderalib.dyndns.org, you would change the link on your main page from »70.128.153.246/cataloging/servle···y+Search to »banderlib.dyndns.org/cataloging/···y+Search you run a client on your machine or router, and the link is always updated without you having to do anything. the nice thing is that if you should later change to some other internet provider, your link will still work.

Hi again David G:

Seems I get to you when I'm over my head. Your great help for
me in setting up that pinhole was really appreciated!

We are going ahead with the upgrade to 25MPS service to the
library. After that is done, I will have the new IP address(es)
and have no idea how they will work--changing often or just
when the modem is turned off/on. Since no domain name is
now associated with the catalog server in the library (I only
refer to it by the internal 192.168... address anywhere in the
library) I don't know how to set up an external domain name
like banderlib.dyndns.org/... . But when the service change
happens, I guess I will figure it out...especially with some help
from this great forum and you in particular.

Thanks again,

Ken Rogers

The att uverse internet uses dynamic public ip addresses, I say again the public ip rarely changes
You can order a "block" of public static ip's for your uverse internet service
