What happens when there are no more ipv4 addresses left?

[hxQ&S8ZaVn9e]

My ISP does not have compatibility with ipv6 and they do not have plans to make it work when I asked. Does this mean that people will not be able to host more websites in a couple years or that the cost will increase a lot so they can be accessed over ipv4?

Get a new ISP if possible.

What ISP is it? Most of the U.S. providers have plans for IPv6 in the near future, unless it's a very small provider for a single city. I use Charter right now and they don't have IPv6 for residential, only business customers, but that'll change soon.

I'll take the pesimistic view here:

ISPs are in no danger. If they wish to procrastinate, they could do so for another 10+ years. If they're running low on IPs, they can simply NAT per exchange (X IPs per 100 people).

People will riot and cause fires, flip over cars and bomb the stores. They will have no way to get their porn and it will cause them to go go crazy. Amazingly though some how the cat pictures will continue to get posted.

The big corps do have a lot of unused ipv4 ips left.

The real IPv4 exhaustion (0 IPs left) will likely be a good few years away if it even happens. Plenty of organisations have unused IP Space which can be sold on or redistributed. AfraNIC for instance still has 42520320 addresses free (/8 x 2.53) and IANA still has ~15 /8's set for future use.

Possible we'll go to a split web.  It's not a terrible idea per se....  Just corporations never have good intentions... soooo....

What is going to happen with IPv4 and end customers?   That's an interesting situation.

Customers can expect to pay more for IP commodity in the near future.   That 20 cent IP value might become $1, per month.  Those are hosting prices, for services in a datacenter.

As a home customer, your IP is already probably abusing you for a static IP and long has.   For instance one of the popular US cable companies charges over $20 per month per static IP.  Will that increase?  No, it's already offensive.

Nothing stopping you from gluing together a work around, tunneling things, using an IPv6 tunnel broker for free IPv6, etc.

I dount that there will be ip exhaustion any time soon. There are many ip's that are unused and can be sold or leased for use.

I know my isp uses ipv6 and ipv4

 

[HBAndrei]

It'll be an interesting time to live in when the day finally comes and we run out of IPv4.

Until then IPv4 prices will continue to rise more and more, as demand is constantly growing while supply is constantly dropping.

 

[Gary]

If a consumer ISP runs out of IPv4 and for some reason can't do IPv6, they'll NAT everyone/new customers and if you need a dedicated IPv4 you'll pay a premium for it.

If the internet runs out of IPv4 and sites start becoming IPv6-only, people will just have to use tunnels to access the v6 web.

Look at those /8 IPv6 nets: https://en.wikipedia.org/wiki/List_of_assigned_/8_IPv4_address_blocks
e.g.: "19.0.0.0/8 Ford Motor Company" 16 million ips...

It may happen that all are assigned - but they are not used.

Yep. Ideally companies like that would be encouraged to re-introduce unused space back in a manner where they could be used if actually needed.

 

[drmike]

Problem is stuff like Ford I'll bet is legacy.  ARIN has no lordship over.

ARIN was offering some reduced rates for your annual fee for givebacks... But such doesn't apply to legacy space.

No one with any sanity is handing ARIN anything back.

 

[MannDude]

That is why I said encouraged and not forced. But encouragement can come from anyone really, but they have no obligation to sell or release any of those IPs from what I understand.

It's not only about hoping that Ford and others give back their /8, it's also about the global routing table is growing a lot. Many of you may remember the 512k day... in a few years we will hit 1M, then the issues will be even bigger.

What I want to say is, that the amount of addresses isn't the only reason to have IPv6 hopefully taking over at some point...

Not sure about Ford directly, but a lot of the older car plants have legacy equipment that isn't exactly capable of using IPv6. To redo an entire line would be expensive and not to mention would take time for each and every plant that would need it.

@wlanboy put a 6 instead of a 4. Legacy configurations/equipment do not need IPV6, they can change their software to use 10.0.0.0/8 instead of legacy ranges.

If I owned a legacy block, there's no way I'd hand it back considering 2/3 of the IPs would probably go to hoarders.

This reminded me when people wondered what will happen to all computers when the year 2000 arrives

Ford actually uses their IP space internally (as do most big companies).  Just because they do not announce it publicly does not mean it is not in use.  They could likely replace it all with RFC 1918 if they wanted, but that could cause conflicts with suppliers who also use RFC 1918 space.
