network addresses

hello,

sorry if this is in the wrong forum, im not sure where to ask.

I'm learning all about networks at the moment, interesting stuff, and I've
come across IP address's which I think i understand, like this 35.98.197.62
is in the class A of ip ranges.

Then I see this

3FFE:1900:6545:15:230:F804:6EBF:C3 which is also some kind of computer
address but I have no idea what for, it looks like it is in headecimal, is
it the same thing as an IP just expressed a different way, or is it
something else?

thanks in advance

Have a Google for IPv6, it's an IP version to overcome the shortage of
IP addresses under IPv4

You can even do a whois of this address. It's assigned to the 6bone
network. I think it's a 3com tunnel for IPv6 over IPv4.

A good read is Novell's Networking Primer (also a pdf download)

except that in 1993, address classes were made obsolete. We're now
"classless". See the RFCS.

In 1995, they started talking about IP Version 6 (the 35.98.197.62 address
is for version 4 that we've been using for many years). There are a bunch of
RFCs, but here's a good place to start:

3513 Internet Protocol Version 6 (IPv6) Addressing Architecture. R.
Hinden, S. Deering. April 2003. (Format: TXT=53920 bytes) (Obsoletes
RFC2373) (Status: PROPOSED STANDARD)

To get these documents, go to any IETF mirror, such as:

http://www.ietf.org/rfc/rfc0000.txt
http://www.faqs.org/rfcs/rfc0000.html
http://www.rfc-editor.org/rfc/rfc0000.txt
http://www.ccd.bnl.gov/network/general/rfc0000.html
http://www.cis.ohio-state.edu/htbin/rfc/rfc0000.html

Replace the four zeros with the FOUR digit number of the RFC desired.
