Solved! Go to Solution.
The home hubs have an inbuilt Dynamic DNS updater where you can enter your DynDNS user name, password, and host name.
If the public IP address changes, the home hub updates DynDNS.
Look under help, A-Z, Dynamic DNS.
Wow - Thanks Keith
Followed your instructions and have inserted my details in my hub
Got the following confirmation on screen to confirm that it was successful
"Dynamic DNS service status: Connected - IP address updated successfully"
There, that was painless
Yes Keith - very quick and painless !!
I have been wondering what to do on this one since June - We were away on holiday and on 2nd day acccess to cameras went down because the BT IP address changed
Had never thought the answer might lie in the BT hub
As you had recently helped on the port forawrding issue re my CCTV I just thought it was worth me running this one past the forum
Glad I did ask as you solved it instantly:smileyvery-happy
Cheers and Many thanks Keith
BT needs to increase its IP address "stickiness" though, so that IP address change is no longer such a problem.
Virgin and Sky also provide dynamic IP allocation, but Virgin stickiness is enormously higher, so high that you quite often have the same IP address for a year or more, regardless of router reboots, network faults, electricity outages, or Trump becoming Emperor of the Known Universe. 😉
It hasn't mattered too much on IPv4, but BT's dynamic non-stickiness is going to be a colossal problem on IPv6 if it continues to work the same way. Hopefully BT realized at design time that that would be a disaster because of IPv6's end-to-end connectivity, and raised the stickiness.
But that's just me wearing my optimist's hat. 😛
