Sure, the 100.64.0.0/10 range is reserved for this specifically, CG-NAT.

No, you get a WAN side IP address from non publicly routable IP address ranges (100.64.0.0/10 is designated for large scale NAT done by ISPs called CG-NAT, the ISP doesn't have to necessarily use this IP pool, and can use 10.x.x.x ranges as well, like few other ISPs) which would obviously be different from your true externally visible IP address.
This is exactly what is happening in your case.

Hi, varkey, do you mean to say that bsnl is now using cg-nat to get me the ip allotment. Is there any way, to check if our bsnl started using cg.nat, which they hitherto have not touched.
I used to get the same ips both in router and on sites.
, normalThat would also be , same first octet in the gateway. Normally i have 117,36,45 etc.But the ips that is given in router tallied with the router.
Is there any check to see if bsnl uses cg nat or is it some kind of a third parties .

It's not just to get you an IP address allotted, it's a full deployment approach. The behaviour you are describing is characteristic of NAT being introduced in between, there is nothing more to check.

No, I don't see an image. You need to select the image, upload and then press the "Add to post" button.
