Does Virgin customer domain name remain the same even if the dynamic IP changes?

I need to know this for monitoring CCTV via the web as I really need the access path not to change.

The domain name is something like:

abc123456-city10-1-1-cust123.15-1.cable.virginm.net which resolves to IP: 12.3.456.78. If the IP changes to 23.4.567.89 will the customer domain remain constant automatically point to the new IP address?

Are customer domains ever changed?

Not sure about a full technical answer to your question.  However, VM dynamic IP addresses tend to be very sticky even if not static.  My VM IP address has been the same since Dec 2020.

I think that the 'domain address' that you mention is the headend that your broadband connection is attached to.

Thank you for the response Graham. I do appreciate that Virgin's dynamic IPs aren't very dynamic but should the IP change when I have no access to check, it would be a tad inconvenient. I have set up access to my CCTV via the IP and separately via the Domain so that if the IP does change and the Domain doesn't, I still have access. I do have an IP monitor program that appraises me of changes but it's not particularly helpful (although it does the job admirably) as I use a VPN. Anyway, it would be nice to reasured that the customer domain is, for all intents and purposes, static.

Easiest way is to buy a cheap domain name and set up DDNS. That’s what I do.

Thanks Tudor. I have several domain names so I'll look into that option.

Its not so use no-ip

Thank you for clarifying. Not the answer I wanted but hey-ho.

Not sure how the Virgin Hub 3.0 can be set to work with DDNS as required by No-IP?

Alas you can't, the VM hubs simply don't have any ability to do this, they are quite feature-lite but designed for a mass market where the majority will never do anything other than use them out of the box.

What you would need to do is have something running permanently on your LAN which monitors the current WAN address and notifies the DDNS provider accordingly.

By the way it's not a 'customer domain' as such, what you quoted in the first post is a reverse DNS entry (rDNS) which points back to your current IP address. The addresses on VM tend to stay static for ages and only really change if there is a network re-segmentation to better balance loads. In which case I would expect the rDNS to change anyway.

Looks like I'll just have to keep an eye on the IP and hope that it is almost static. Thank you for your help. Much appreciated.
