Well it could be many things, but the example below is one option-
::EAT0:BEEF:4.2.2.1 |

said by Mutiny32  :What is 4.2.2.1 in IPv6? Technically it's 0:0:0:0:0:0:402:201 or ::402:201 but its not that simple. Plus the 4.2.2.* Server are not root server, anyways I highly doubt they are IPv6 enabled.
But that truly just uses IPv4 Networks. |

"tracert ::EAT0:BEEF:4.2.2.1" dose not. Not saying its not right but... meh. |

said by pkarlos_76 :Could anyone explain the benefits and the disadvantages of IPV6? Advanatges are that every device will be able to have its own address - even devices without a human interface.
Biggest disadvantage is the conversion process and all the problems that will result from running IPV4 & IpV6 side by side:

Advantage: 128bit addresses instead of 32bit allow for trillions of addresses (ie bye-bye NAT!)
Disadvantage: You now have to remember 2001:0db8:0eff:87a0:27bf:0000:1428:57ab instead. |

From IPV6 Wikipedia article:
"A sequence of 4 bytes at the end of an IPv6 address can also be written in decimal, using dots as separators. This notation is often used with compatibility addresses (see below). This addressing scheme is convenient when dealing with the mixed environment of IPv4 and IPv6 addresses. The general notation is of the form x:x:x:x:x:x:d.d.d.d where x's are the 6 higher order hexadecimal digits whereas d's correspond to the decimal digits of lower order 8 bit pieces of address, as it is the IPv4 format. For example, ::ffff:12.34.56.78 is the same address as ::ffff:0c22:384e and 0:0:0:0:0:ffff:0c22:384e. Usage of this notation is deprecated and unsupported by numerous applications."
Note that last sentence, which means IPV6 in winblows is one of those "unsupported" configs... thanks MS!

said by Mutiny32 :What is 4.2.2.1 in IPv6? Nothing, since IPv4 and IPv6 are not compatible. That's the biggest hindrance to the transition to IPv6.
The solutions are to run a "dual stack" where everything is on both Ipv4 and IPv6 with gateways in between, or utilize translation software in network hardware to facilitate the communication between IPv6 devices and IPv4 devices.
There certainly is no easy migration path. |

HUH? You are willing to expose every single piece of hardware you have in your network to the Internet? Do spend all day and night making sure all your OS's are secure? |

| ISP's charge per ISP because they can....but also because IP addresses are at a premium because they are in limited supply. ISPs also may only have a limited block of addresses that they can allocate so in order to ration them, they charge extra.
With IPv6, all the supply issues go away. A 128 bit address space, you literally could give an ip address to every grain of sand on the planet and still not run out. Every person/subscriber in the world could get their own block of 1K addresses to allocate as they want and there would still be more addresses then anyone knows what to do with.
Now that doesn't mean that ISPs won't still charge for them, but they won't be able to use the excuse that they are in limited supply. Dynamic addresses also could go away . It would only be a matter of the ISP updating their router tables for new customers as they sign up. |

Hmm BYE BYE to claims by the ISP's they don't know who the IP addres belong to........US poor P2P Pirates that are P2P'ing Ubuntu Linux OS's, World of Warcraft updates, Joust, and Vuze and others can't hide no more.  |

The same reasons why ISPs don't track DHCP users now will exist with IPv6...they choose not to. It's a headache for them not only from a technological reason, but also with record keeping, legel requests, etc. It's much easier to turn a blind eye, shrug your shoulders, and say "Sorry, we don't keep track of that" then deal with all the crap if they did. Just like most businesses, if it costs them money and it's not required, they aren't inclined to do it. |
