IPv6 Adoption Up 300 Percent Over 2 Years
Mark.J - ISPreview writes "The Number Resource Organization, which is made up of the five Regional Internet Registries, has revealed that the rate of new entrants into the IPv6 routing system has increased by 300% over the past two years. The news is important because IPv4 addresses (e.g. 123.23.56.98), which are assigned to your computer periodically, are running out. IPv6 addressing (e.g. 2ffe:1800:3525:3:200:f8ff:fe21:67cf) was invented as a longer and more secure replacement." IPv6 is still gaining ground slowly, particularly in the US.
God, I'm tired of it being repeated that IPV4 addresses are running out. Everybody who's not a journalist should know that it's not true.
And everyone who's a network admin knows that it is.
Nat+uPNP is perfectly capable and 100% backwords compatible.
Great, so I can re-write every application to support a half-assed workaround like NAT. I'd much rather have each host bugging the crap out of the router to forward a specific port, please! than to just get the migration over with and be done with it. If you think that NAT+uPNP is a replacement for IPv6, then you need to find a hobby more suited to your skill level.
Dewey, what part of this looks like authorities should be involved?
Nat+uPNP is perfectly capable and 100% backwords compatible.
NAT is a hack, and uPNP is not universally supported -- not in the routers themselves, and not in every program you might want t ob accessible.
Besides which, there are a limited number of ports, and you're still preventing people from picking a standard port and leaving it open, to connect to it later -- for instance, if my ISP NATs me, how do I ssh or vpn back home? Let alone run a webserver out of my house..
That's not even getting into all the millions of unused IP's being held by the early internet companies.
True, but consider that IPv6 would prevent anything like that from happening again.
Start with $1 per year per ip to EVERYONE who owns an IP's and you'll see the "IP Shortage" vanish overnight.
I'd also very likely see my own public-facing IP go away, and more and more ISPs NAT-ing all their customers -- who are then doubly-NATed behind their routers -- which is then a gigantic pain in the ass to deal with, versus simply upgrading to ipv6.
I'd also likely see my hosting costs go up a bit.
All to manage this artificial scarcity, and push it back for awhile -- which could be so easily dealt with by simply upgrading to ipv6, and giving an IP address to every device on the planet -- and, as a nice side effect, making it possible for me to assign a public-facing IP address and DNS entry for every toaster in my house.
Don't thank God, thank a doctor!
Most machines don't need an externally accessible IP.
Which has nothing to do with the IPv4 vs IPv6 debate. Regardless of which stack you use, you are never forced to have externally accessible IP addresses. This is what firewalls, routers, and reserved, non-routable addresses are for.
Lots of them.
Any kind of webserver. Try running two of them on the same IP address.
Of the above, especially websites using SSL. Can't have more than one per IP address.
FTP is a horrible pain when NAT is involved.
Many video conference applications.
Programs like instant messengers with file transfer.
BitTorrent and any form of P2P in general.
IPsec in transport mode
Many games. Two players trying to play online doesn't work at all with some games, no matter how much you fiddle with NAT.
Remote desktop. When troubleshooting, I can't just ask the person I'm helping to install VNC, because then I'd have to explain to them how open the port.
I'm sure the list can get a good deal longer, but this seems enough.
If something increases by 0%, that means it stays the same, not disappears completely. If something increases by 100%, that means it doubles, not stays the same. Induction can take it from here.
