IPv6 Static IP Block changed by Comcast after modem swapped by tech
On 3-31-20, a Comcast Business tech switched my modem for some kind of upgrade that had to be done, and now I find that my IPv6 Static address block has been changed.
My block of 5 IPv4 static addresses are still OK and the same.
The old modem was a SMC model SMCD3G-CCR, and the new one is a Cisco model DPC3939B.
THIS causes me a hassle, WHY was this changed?
