WAN IP is private IP ??

[unclebuk]

Although my ISP modem is set to bridge mode and I use PPPoE to connect to the ISP on an Asus router with Merlin f/w, just recently the WAN IP is now a private IP, (10.144.99.117), NOT a public IP issued by the ISP I usually see.

I made no changes to anything aside from installing diversion.

How is this possible and what could be the cause of this anomaly?

Thanks in advance for any assistance in understanding and resolving this.

Regards,
buk

Probably changes made by your ISP to their infrastructure. I suspect you need to talk to them about it as it's not something you can control from your side.

I stumbled along the issue of CG-NAT (carrier grade NAT) which I believe now is what has transpired in my situation. My ISP does not speak good "technical" English and I have put off calling them to confirm this abberation, which on the surface appears to be very common procedure undertaken by ISP's world wide. Case closed at this point.
Thanks for your input Mr. Taylor.

Yep - when I was in the Telco Business - all subs got private addressing for ipv4, and we did have a range that was moving over to CGN with migration to 4G-LTE and full ipv6 transition...
