My public ip address is rapidly changing (roughly every 10 seconds.)

this is happening on all devices.

My devices ip addresses are stable,

I have a HG659b modem which I believe to be properly configured. This modem has also been replaced and factory resetted.

The DHCP lease renewal time for my device has been set to a day.

If you guys need any other information let me know.

Is the xDSL dropping off often? Also check you have the latest firmware on the HG659b

This sounds to me like a standard disconnections issue.

What sort of connection do you have?

What area are you in?

I'm assuming as the modem was replaced, you have spoken to the center, what did they say they could see?

I don't believe this is a disconnection issue. Spark has tested the line to indicate no dropping or micro disconnections, same with a seperate speedtest. I am also having no performance issues in terms of general use.

I have a VDSL connection.

Rural Waikato.

I will check for firmware updates tonight as I am currently away from home.

Interesting, connection will have to be dropping to be changing IP.

How are you testing your IP is changing?

Can you DM me your line and i'll sanity check it.

I'm testing the public ip address through various ip checkers online such as:

https://whatismyipaddress.com/

etc

I had an issue many years ago with Spark where they had cached a bunch of "what is my IP" sites so it was showing me someone elses IP address instead of mine

It was actually a Geekzoner from Spark that got to the bottom of it for me..

Bluecoat is nolonger used.

Really cool tech, but the issues with it are annoying to say the least..

Is this the IP that your router shows you being assigned? I'm thinking of the case where the IP address in the browser differs from the one assigned by Spark due to VPNs or filtering in your browser, or a transparent proxy (although I don't think any ISPs use this anymore)

I can confirm the router IP is being shown in the ip checkers.

PM me your account number and I'll see what the RADIUS logs are saying.

[edit - please send through a few examples of the public IP you are being assigned, and confirm your sync speed and whether you are ADSL2+ or VDSL. I know you've already said you're on VDSL, but please check in the modem stats page to absolutely confirm]

Cheers - N

As suspected this was a simple missjumper.

i do wonder why the issue only just surfaced as it appears the ports have been confused for quite some time!

Few extra things to look into from the OP's side, you have a DM about that :)

From my end, connection is now rock solid and showing everything correctly.

This was a weird one, as to the normal eye, the reported issue wouldn't line up with reports and look like wifi issues rather than the actual problem!
