Can someone explain why my modem and ipconfig give me two different IP6

When logging into the web server internal to the modem to look at
devices, are you looking at the LAN-side (aka intranet) IPv6 address the
modem's DHCP server assigned to the device (or what the router reports
if the host uses if using static addressing), or are you looking at its
WAN-side IP address (the public address that all external/Intranet hosts
will see)?

Does that public IP address match on either the IPv6 addresses you noted
above? If so, that's the WAN-side IPv6 address of your router, not the
LAN-side IPv6 address of your intranet host.

When I go into my modem and click on the device listing for my host, its
IPv6 address, local link IPv6 address, and MAC/physical address match
what "ipconfig /all" reports on my host.

Do you have multiple NICs in your host? I don't have bother Ethernet
(wired) and wi-fi in my host, so I can't see how the modem reports the
different IP and MAC addresses for each NIC but I assume they would be
different. The PC came with a wi-fi daughtercard but I removed it
because it's a desktop, doesn't move, I prefer the simplicity and
security of a wired connection, and anything wireless that wants to
connect to my PC can do it through a wi-fi connect through the modem.


Configuration:
Windows 7 Ultimate SP1 (x64)
Motorola MB7220 V1.0 cable modem with firmware version 7220-5.7.1.9
Modem accessed through a Netgear N300 Wireless Router WNR2000v5

When I logon to the modem and request the advanced display, I can see
the following:
IPv6 Address 2605:e000:c04:7b:e855:8b57:644f:706d

Selecting the circled "i" for more information, I get:
IPv6 Address:
Assigned to your cable modem by your cable provider. The assignment is
referred to as a Lease.
IPv6 is a newer, longer style of IP Address. Your cable provider may
assign an IPv4 Address, an IPv6 Address, or both.

Note: Both IP6 addresses are "owned" by Spectrum, which is my ISP for
connecting to the Internet. (When connected, I use a different ISP for
E-mail and hosting my Web site.)

government sources said there was no recent evidence of terrorism
suspects being caught along the border." Reuters News

I think Trump is the primary source of the fake news he condemns.
