AT&T U-Verse Internet - External IP Address change?

Lilian 1,124 45 December 12, 2011 at 02:46 PM
I seem to be getting two different answers from U-Verse customer service and the research I did online, so I'd like to get input from someone who has U-Verse service.

With AT&T DSL, it's possible to get a new external IP address by restarting the modem.

Is it possible to get a new/different external IP address at will with U-Verse? AT&T reps say yes and online forums say no. So what's the correct answer?

Please help....

I cannot answer for your circumstance directly, but to get a new IP in most cases you usually either need to shut down the modem for some amount more than 24 hours (exact amount depends on the dhcp server settings used by your provider) or change the MAC address of the device (swap routers) behind the modem and restart the modem.

Note your IP address.

Unplug your modem for 10 seconds, then re-plug it back in.

If it is a new address, you have dynamic. If not, its static.

Thanks. Unfortunately, I haven't switched to U-Verse, so I don't know how the IP address situation would work out.

ahhh. Well, from my experiences most ISPs will only give you a static address if you purchase a Business plan. But that probably doesn't help that much either.

Iagree

You would have to pay more for a static IP address. Uverse works pretty much like DSL in that Dynamic IP's are given and usually every 24 hours.

Not sure if this is helpful, but the customer rep mentioned I can get DHCP or a static ip. Is this in anyway related to the external ip address?

Very much so. The question is how often will the DHCP address change and under what conditions.

Do you happen to know how this would work with U-Verse? Would I be assigned a new external IP every once in a while? Would there be a manual way to change / reset / get assigned a new one?

Thanks.

I would think it would be the same process. Dontknow

Uverse is dynamic, but you have to jump through hoops to get it to get a new IP. The most success comes from disconnecting the RG right before the lease is going to expire, do a factory reset on the RG then connect it after the lease expiration. At my previous house I had the same IP for several years until I turned the power off to the house while it was being fumigated. When I came back it had a new IP. In my new house I tried forcing a new IP because the one I had was freaking out my dyslexia and I couldn't remember it to save my life. I finally disconnected the RG for a week when the family went on vacation, did a factory reset before plugging in the upstream wire, plugged it in then magic, I got a new ip.

The better question is where did you get banned from that you need a new IP to get into? Big Grin

The "D" in DHCP is for Dynamic...as in it changes.

Static means that is does NOT change.

Most times you have dhcp and by chance when it renews...the server just hands you the same ip address each time and so you are unofficially static...but it's not guaranteed to stay the same.

The big question is...why do you care if you have a static or dynamic ip address anyways?

If we knew the underlying answer to that, then we could better help you out.

Aha. You're exactly what I'm looking for!

So the big question is: Is there a way to determine when the lease expires so you can time the reset of the RG? And is it really necessary to wait for days before reconnecting?

Also, let's answer that "better question". I'm not banned from anything but SD'ers know sometimes it's nice to be able to get a new IP address on a whim.

Sounds about right. I'm trying to figure out how this works U-Verse which is VDSL. Just curious, what type of DSL do you have and how does this work on your connection?

In the link tree You'll need your system password. http://192.168.1.254/xslt?PAGE=C_...2&MODID=24

or go to diagnostics, link tree, click on dhcp0 under the bband0 link then look at it below.
pm_bb_dhcpc
Dependency State: UP
Link State: UP
Link Detail: UP

File Descriptor flags: 00000001

REBIND: Sun Dec 18 18:13:14 PST 2011 +140.1 hours
EXPIRES: Tue Dec 20 12:13:14 PST 2011 +182.1 hours
SERVER: @ 00:16:4d:82:a3:5c
LAST SERVER UPDATE Fri Nov 18 03:50:54 PST 2011 (past))

The only problem is I'm not sure to try it around the renew, or the rebind date. and that's a pretty long date which is why turning off the modem for a day does nothing. Back in the regular dsl days dhcp lease was usually 24 hours at the most.
