But that truly just uses IPv4 Networks. |

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

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/4ba2.02···rop.html -- Internet News My BLOG My Web Page |

Disadvantage: You now have to remember 2001:0db8:0eff:87a0:27bf:0000:1428:57ab instead. |

| reply to Napsterbater 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 |

1 edit | reply to Mutiny32 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 BETTER
IPv6 --> 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.

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? |

| Too many privately held Class A addresses
What 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 |

Yep, IPv6 spells the end of the wild west lawless (i.e. uncontrolled) internet as we know it, and THAT is why it is being pushed. -- The public is a poor business manager. |

| reply to elwoodblues Re: Too many privately held Class A addresses
Your math is completely wrong. The maximum number of addresses for IPv4 is just above 4 billion. Attempting to recliam some netblocks would only be a very short term workaround and only benefit North Americans, there are other countries where IP addresses are necessary and in very short supply. |

No, you have to spend every hour of the day and night configuring your firewall to allow access to everything.  |
