Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

RIPng ("RIPv6") Message Format and Features
(Page 1 of 3)

The future of TCP/IP is the new Internet Protocol version 6 (IPv6), which makes some very important changes to IP, especially with regard to addressing. Since IPv6 addresses are different than IPv4 addresses, everything that works with IP addresses must change to function under IPv6. This includes routing protocols, which exchange addressing information.

To ensure a future for the Routing Information Protocol, a new IPv6-compatible version had to be developed. This new version was published in 1997 in RFC 2080, RIPng for IPv6, where the ng stands for next generation (IPv6 is also sometimes called “IP next generation”).

RIPng, which is also occasionally seen as RIPv6 for obvious reasons, was designed to be as similar as possible to the current version of RIP for IPv4, which is RIP Version 2 (RIP-2). In fact, RFC 2080 describes RIPng as “the minimum change” possible to RIP to allow it to work on IPv6. Despite this effort, it was not possible to define RIPng as just a new version of the older RIP protocol, like RIP-2 was. RIPng is a new protocol, which was necessary because of the significance of the changes between IPv4 and IPv6—especially the change from 32-bit to 128-bit addresses in IPv6, which necessitated a new message format.
