Main features[ edit ] Decomposition of the IPv6 address representation into its binary form IPv6 is an Internet Layer protocol for packet-switched internetworking and provides end-to-end datagram transmission across multiple IP networks, closely adhering to the design principles developed in the previous version of the protocol, Internet Protocol Version 4 IPv4. It simplifies aspects of address assignment stateless address autoconfigurationnetwork renumbering, and router announcements when changing network connectivity providers. It simplifies processing of packets in routers by placing the responsibility for packet fragmentation into the end points.
Does this mean I'll need extra protections so my router would not automatically start advertising these private IPv6 addresses to the world? The RFC that covers these ULAs RFC specifically states that these numbers should not be routed on the internet, though two peers may mutually agree to pass certain prefixes.
Unless Comcast decides to unilaterally route these unlikely in the extreme you should have no worries about route advertisement. This means that their now-running IPv6 testers have the option of running with globally routeable addresses, but firewalled by their router, or do some kind of NAT with either link-local or unique-global-addresses.
However, running without any kind of address translation is not as insane as it sounds. Keep in mind a few points. Four billion times four billion. While the nature of IPv6 autoprovisioning reduces the actual number of addresses that need scanning, scanning it is still infeasible.
This greatly reduces the ability of attackers to recon your network. Running without NAT makes certain network problems easier, and certainly makes undesirable but very popular peer-to-peer technologies you know what I'm talking about a lot easier to get up and running.
Running without a firewall is still just as insane as it sounds, though.
Happily, you can do firewalling without having to NAT. Second question, what's this link-local thing? Think of it as able to reach anything in the current broadcast domain, and can not be routed.
In fact, if your home network is completely flat you can use these addresses instead of Unique Local Addresses. Third question, what is scope id for? It's used for two different things, which makes it annoying to describe: It defines how far the multicast packet is intended to reach.
It's used primarily with link-local addresses. It should never be used in conjunction with CIDR notation, so the two syntaxes should never be combined.WHITE PAPER: Creating an IPv6 addressing plan is one of the most important pre-adoption tasks you have.
|IPv6 Forum :: Driving IPv6 Deployment||This document describes a protocol for automating the process of creating Network Address Translation NAT port mappings. Included in the protocol is a method for retrieving the external IPv4 address of a NAT gateway, thus allowing a client to make its external IPv4 address and port known to peers that may wish to communicate with it.|

Essay Paper on IPv6 The promise of IPv6 lies in its vastly increased IP address space, and the resulting opportunity for us to abandon Network Address Translation (NAT) and clear the fog on the Internet which obscures our vision for global peer-to-peer networking.
