What you need, @njr1972 is DDNS. You register with a DDNS provider that is compatible with your router (some are free). This will give you a domain, the provider tracks your domains's WAN IP address & updates itself as it changes. For incoming port forwarding etc, instead of specifying the router's WAN IP address, you specify the domain name.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here
