Me and 1and1 fell out after they sent debt collectors to chase up expired credit card details so I want to sack them off.
I see the Plusnet Hub One router supports Dynamic DNS. As far as I'm aware it means I can point DNS names at a dynamic (changing) IP address.
I was wondering if anyone had any experience of using this and could recommend a service? I've not seen any hosting .co.uk domains unfortunately.
Thanks.

It's free but your domain can be used by anyone for sub domains unless you subscribe to a paid package.
I've used them for years and been quite happy with it.

I create a CNAME DNS record to point a sub domain of mine to the DDNS hostname. That way I can use eg. home.mydomain.co.uk to access my services, instead of the free hostname I'm assigned by no-ip.

I don't know if you can do it through the router, but anything that's similar to task scheduler / cron that can run cURL or Wget can update the IP periodically via their API.
Up to three domains (each with unlimited records) is free, then £3.50/mo get's you a configurable TTL (compared to free which is 1hr) and a bunch of extra stuff like email forwarding, analytics and 14 (speedier) DNS servers
Link to their comparison page: https://www.cloudns.net/premium/
Of course, a static IP is a one-off so it's probably your best bet

Quote from: Bob Out of curiosity, why do you consider CNAME records ill-advised?
I realise my original post was a little ambiguous, so to add clarification:
My previous solution was to use FreeDNS (i.e. mysubdomain.freedns.afraid.org pointed to my dynamic IP), then add a CNAME record as the root record for my site, which pointed to mysubdomain.freedns.afraid.org. In addition to that CNAME record, I also had MX records and other, different, CNAME records for subdomains, which AFAIK goes against some web standards (even though it does work okay in practice).
I suppose it's one of those things I've never really questioned, like when a chemistry teacher tells you not to smell ammonia or something. Not a clue what will happen - maybe nothing, probably something bad - but you tend to follow the advice. In my case, Gandi wouldn't allow CNAME records as the root record of a domain, stating simply that it goes against DNS standards. Since then I've stopped using them like that, even though some DNS providers let you.
Googling it shows that it is in accordance with RFC 1034 (https://www.ietf.org/rfc/rfc1034.txt), in particular section 3.6.2:
Quote from: RFC If a CNAME RR is present at a node, no other data should be
present; this ensures that the data for a canonical name and its aliases
cannot be different. This rule also insures that a cached CNAME can be
used without checking with an authoritative server for other RR types.
Which doesn't actually state that A records must be the root record, or that CNAME records cannot be the root record, but that if a CNAME record is the root record then no other records can be present (I think).
Finding this out was actually what caused me to start using the free version of ClouDNS, as Gandi didn't have an API for updating a dynamic IP like some providers do
