Origin Fibre Broadband


[link to this post]
 
A couple of words of warning on Origin broadband.

Origin use CGNAT so your router does not have a real world IP address.

This will have implications for anything that relies on port forwarding.

The additional address translation will obviously have an impact on latencies, etc.

But it is likely that a bigger problem is that the real IP changes, systematically, every five minutes.

Your router’s IP address wont change but the rest of the world will see you changing IP address every five minutes.

Caveat emptor.

A static IP can be added for only £1.49 per month as an add-on.

From the page you just linked...

Every customer is given a dynamic IP address for free. This means that your IP address could change from time to time without affecting a typical customer's service.


Every customer isn't given a dynamic IP if they use CGNAT.

Thank you OP, useful info.
I'm sure it will be enough to put a few people off.

It is a dynamic IP - it just isn't a public dynamic IP - they are correct but appear not to be mentioning that you couldn't use the dynamic IP for incoming port forwarding.

If you think this statement is correct for CGNAT then I don't know what to say...

That's clearly pre CGNAT usage.

They could DHCP with short lease times on an RFC1918 address, but why would you??

I think the newer and smaller ISPs will all have issues with IPv4, look at Hyperoptic whom have been around a while. If the ISP doesn't also provide IPv6 then I would personally not choose them.

The customer will have a dynamic IP address assigned - but it will be an internal private IP rather than a public IP - the router still needs an IP to be able to be addressed over the network.
