Vodafone Sticky public IP Address

Hello forum.
Does anyone have Vodafone (residential) Broadband, using their Ultra Hub?
I have had an installation that I've had a few stability issues with so I have a BQM set up.
Thing is, the public IP address seems to have changed at least twice in the space of a month. I know it isn't a fixed IP address, but it should be sticky enough to stay the same for a long time , should it not? Anyone have any ideas why it might change more frequently, or know of any configuration on the Ultra Hub that might affect the stickiness of the lease?
Any help much appreciated

You can’t really complain, it isn’t static.

As to why it’s changing, well are the issues you mention causing dropped sync ? If so, there’s your answer.

Thanks for responding Zarjaz.
To be fair I wasn't complaining, just looking for answers.
If by "dropped sync" you mean a total loss of connection between my router and it's gateway or whatever is the next device up the public network, wouldn't it usually be served the same sticky address when it reconnects? I only have the BQM to go on at the moment and it goes from a very stable graph for a period of time to 100% packet loss which seems to be the point at which the IP address changes . Any advice on what else I can look at around the time that it drops would be very much appreciated.

Can you physically see the router ? Then check what lights it is displaying when the connection drops

According to Vodafone's price list a static IP is free. Perhaps ask them for one?

Sadly not Zarjaz.the installation is in a rental house so I'm trying to diagnose it remotely. I can harvest the logs, but wouldn't know how to interpret them. I'm fairly sure that it reconnects without intervention.

Good spot behuk....I'll look into that

Or check to see if the router has dynamic dns support from the likes of no-ip, dyn.com, etc. BQM supports hostnames.

Many ISPs dynamic IPs are not sticky and will change on any reconnect.

ISPs can reboot their BRASes overnight for upgrades etc. That will cause all sessions to drop and re-establish, and you'll get a different IP address.

A couple of times a month sounds pretty reasonable.

The usual way to deal with this is dynamic DNS - your router updates a DNS entry with a DDNS provider when the session restarts.
