Re: So...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: » ntrg.cs.tcd.ie/undergrad ··· rop.html | |

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. | |

Do spend all day and night making sure all your OS's are secure? | |

Re: So...Huh? Was this supposed to be sarcasm?
To the poster above.. learn how to use a firewall properly. Posting comments like that shows you need a clue bat. | |

Re: So...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. | |

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

Start -> run -> cmd -> "tracert ::402:201" Works "tracert ::EAT0:BEEF:4.2.2.1" dose not. Not saying its not right but... meh. | |

Re: So...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! » en.wikipedia.org/wiki/IPv6 | |

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. | |

Glue Records?I want to know when we'll be able to add IPv6 addresses to our Glue records. As of right now, I'm not sure anyone does, which is again, a missing key in DNS, for PURE IPv6 domain. I have a domain that I use solely with v6, and this helps in some ways, but yea..
For those giving memorization as a big factor of not adopting: Get Over It! There are IPs like 4.2.2.2 that we just know (because its simple), but then you have ones like (random) 216.193.78.158. Just like anything, it takes a while till you pick up the sequences, but you do. Most of the v6 addresses I deal with I have memorized (then again, they aren't that long .. yet) | |

IPv6 can TRACK you BETTERIPv6 --> advantage: they can track you unequivocally, one day, NAT no longer necessary, every device in the world WILL have a unique IPv6 address, whatever and whenever you do on the Internet can be proven, case closed=your busted, try blaming it on your kid or an open wi-fi connection won't be possible. Your fingerprint IS the DEVICE itself.

Re: IPv6 can TRACK you BETTERStupid "Brad",
They can now can use a IPv6 OR a MAC address (forged or not forged) to form the basis for a search warrant, to recover further evidence. Nothing is absolute, and most criminals aren't smart/wealthy enough to create multiple layers of anonymity. | |

I smoke more than that Seriously though, if they use IPv6 to "figerprint" you, the evidence will not hold. Since we can forge MAC addresses, we can easily forge IP addresses. Unless they use digital certificates in the devices... | |

Re: IPv6 can TRACK you BETTERMost do not go through the trouble.The "fingerprint" is the "beginning" of the investigation. Once they get ahold of your laptop, then your done. Don't tell me about encryption and what not... There are ALWAYS measures and countermeasures for everything. Go smoke some "pot". I heard its easily purchased and not enforced at where you live, so be happy and get yourself "stoned". | |

Too many privately held Class A addressesWhat kills me is that everyone runs around saying we are running out of IP addresses.
Really?
Lets see from 1.x to 10.x 4 are reserved the 3.x IP range is given to GE (do they really need an entire Class A address?)
Level 3 has 3 complete Class A addresses The DOD has 2 Class A addresses IBM has entire class A address
Now I'm not saying take all the privately held Class A address space away, but unless I've done the math wrong we have 42,282,506,250 addresses available in just the 1-10.x Ip range.
thats 42 BILLION | |
