TEREDO? IPv6 sys

Anyone know what the following might refer to? It's an
internet attempt to send a packet, but it came about
without, near as I can tell, my ever having loaded or
changing anything. Since it started to happen it occurs
every time I log into email. Probably nothing important,
but since I don't understand it, thought I'd check here.
First glance I thought it was an intranet thing, but ...
it's trying to go out on the internet.

TIA

Teredo, also known as IPv4 network address translator (NAT) traversal for
IPv6, is an IPv6/IPv4 transition technology that provides address assignment
and host-to-host automatic tunneling for unicast IPv6 connectivity when
IPv6/IPv4 hosts are located behind one or multiple IPv4 NATs. To traverse
IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP)
messages. This article provides an overview of Teredo-including Teredo
addresses and packet structures-and detailed explanations of how
communication is initiated between Teredo clients, Teredo host-specific
relays, and IPv6-only hosts using the IPv4 Internet, the IPv6 Internet,
Teredo servers, and Teredo relays.

Darn! Why couldn't I come up with that? Guess I just
didn't hold my mouth right. Than ks!

FANtastic, John! Not only were a LOT of the IP addresses
used in there familiar, but the Introduction straightened
out everything in my mind. NOW I almost understand. At
first I was pretty confused by the excerpt you pasted, and
not much of the article made sense to me except that I don't
have a NAT router, but the Introduction link puts it all
into a perspective I can live with and at least feel a
minimal understanding, meaning, enough to be dangerous! <g>

If anyone following this is interested at all, that link
contains the Introduction link I'm referring to and I highly
recommend reading it, especially if you're interested in the
running out of IP address ranges. .
