When will we run out of IP Addresses?

2	Since there are only a select number of IP Addresses, when do you think that we will run out of them? ip shortage address asked Jul 28 '10 at 04:25 catchatyou 20.7k●89●165●383

I read on CNN that we'll run out of IPv4 in September 2011, but we can just change to IPv6, which isn't too hard to do.

Yeh. They'll probably phase people over and start using IPv4 addresses for dedicated hosting, tunnelling or users who want to pay extra.

You could Google it to find the answer is a topic human carbon units talk about, so you would most likley find an article on it. Well once we hit 999.999.999.999 then we are out. But I heard IPv6 has a fix for this. The number of addresses is limited because of the amount of bits that can be used for addressing (basically putting the address of where the packet is going) all packets are a standard size that is why they have a restricted amount of bits for addressing. IPv6 has more bits for addressing so they can fit longer addresses so you have more addresses.

yeh a standard IPv4 ip adress is upto 12 digits, so 999,999,999,999 is the limit to the number of them, but the new IPv6 is layed out as letters and numbers and i think they can be longer, so will be more availability, but i dont doubt we will have to upgrade again in my life time

and what happened to IPv5?

Not a clue thought of that though as I was reading your comment. lol Google time!

Actually, it's not 999.999.999.999. IPv4 addresses are usually represented in dot-decimal notation (four numbers, each ranging from 0 to 255 -- same range as todays octet/'byte', separated by dots, e.g. 208.77.188.166). 255.255.255.255 is reserved, as is any IP on the 0.0.0.0/24 CIDR, the 127.0.0.0/8 CIDR and a few other ranges.

Another protocol uses a 5 in the version field of an IP packet. If IPv5 were to use 5 in the version field there, there would be a conflict. My guess is they decided to skip version 5 in lieu of this.

ok :P and yeh i didnt think of the range to 255 LL and if we had things on different ports that would allow for more services, but make things more complicated :P but still

(Jul 28 '10 at 04:49) Tim Fontana

What do ports have to do with services? Neither IPv4, IPv5 or IPv6 use ports. You're talking about TCP and UDP.

showing 5 of 7 show all

Not any time soon. IPv6 has enough IP addresses to last at least another 500 or 600 years.

According to this rather misleading chart, IPv4 will run out of IP addresses in the next couple of years. What I want to know is, what makes them think IPv4 had 275 free /8 CIDRs in 1996? That can't be right!

misleading!

0	I have read that it is about a year. IP6v should last hopefully at least 5-7 years, but Ime not sure on that. answered Jul 28 '10 at 12:40 franklinonline 31●2
