One of my clients has just shifted house and took their Spark fibre + landline (VIA ONT) along to the new address. I have them setup with noip (Dynamic DNS) and DNS4me so that their Roku box can access overseas content. All has been fine for years, until their shift. Their HG659B reports an IPV4 address of 100.65.239.XXX (a non-routable IP) which is sent to noip.com but this isn't their real IP which happens to be 203.211.74.XXX when checked at whatismyip.com. Obviously DNS4Me refuses to accept this address in their IP Access zones so their service fails.

This leads me to believe that Spark have started to use CGNAT on new connections? Does anyone know what's happening here?

No. No CGNAT on fibre connections. Are you sure that the service they are getting is from Spark and not from a previous RSP at that address? Can you get them to run a speedtest and see what RSP Ookla thinks their IP is?

203.211.74.xxx is a Devoli address.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

That will explain it. Their account is with Spark, and their landline from Spark went live today (via the ONT) as was their fibre, so I simply assumed their fibre was via Spark today also. I'm assuming they must actually be getting fibre from Devoli (Contact or similar) as that was used by the previous tenant? Perhaps this will be switched by Spark this week?

Or Spark is activated on Port 2 of the ONT perhaps?

As above, try port 2. When we switched from 2degrees to Spark they did this and said it's easier than timing the disconnection from the old provider.

@Spong, in case you're wondering, I've removed your other thread. This is the appropriate sub-forum, and one thread is sufficient. Cheers and thanks!

Thanks for the heads up guys. I'll need to call in and check as the owners are in their mid 80's and standing on their head to swap ONT ports would be challenging to say the least!

Once previous owners connection is disconnected then it will stop, best to check port 2 sooner rather than later.

Confirmed Spark fibre was live on Port 2 of the ONT, and previous tenant's connection still chugging on Port 1. All sorted now. Many thanks for the excellent support with this guys!
