If I could NAT my gas tank the world would be a very different place.
i.e. ride the bus?
That's not NAT, that's everyone looking at one computer screen scheduled to visit the same 10 web sites repeatedly all day.
Whatever happened to the IPv4 address crisis?

Re: Whatever happened to the IPv4 address crisis?
#92This is an interesting article, but it contains some rather surprising innumeracy in its cavalier comparison of 2^128 to the number of grains of sand in the earths crust. 2^128 is an enormous number, roughly 3.4e38:
2**128 = 3.4 * 10**38
grains of sand to one mile down [1] = 5.1 * 10**26
stars in the observable universe [2] = 7.0 * 10**22
estimated grains of sand [2] = 7.5 * 10**18

Re: Whatever happened to the IPv4 address crisis?
#93It's here. IP addresses are costing more and providers are less generous with them. It used to be common to get a handful with a dedicated server, now you get one or two. I have a friend who runs a small low-cost minecraft hosting. He stopped giving his customers dedicated IPs at all. They get a range of ports and a hostname with appropriate srv records added. That's the other result, technical work-arounds. You can…
SRV records are terribly underused/underimplemented
That will change if, and probably only if, we can get https://github.com/http2/http2-spec/issues/381 off the ground.

I am curious. Which other criterion than IP address could they use to prevent anonymous users from Qatar from vandalizing? (I guess one method could be to force everyone from this IP address to create an account, but that goes against their openness/ease-of-editing-for-new-or-casual-users principle.)
I mostly object to the phrasing that Wikipedia is "forced" to block all of Qatar, as if Wikipedia is a mindless force of nature or not in control of its own actions.
Finally someone sticking up for wikipedia around here. Its disgusting the way She is treated.
Re: Whatever happened to the IPv4 address crisis?
#95The main problem the 20 years ago with the take off of the internet as a mass networking standard it was blindingly obvious that ipv6 was deeply flawed - IPv6 should have been taken out behind the woodshed back then and ipv7 or 8 done properly. When I looked at it 19 or the 20 involved in the RFC for ipv6 where from academia plus one guy from bell labs. Migration and Interpenetration should have been the highest prio…
Maybe. Or maybe we will suffer tremendous amount of pain for some period of years after which we will have a much brighter future as opposed to an ipv7 that made too many concessions and left us with a mess that would be politically impossible to ever fix.
mm yes or maybe know when to let a flawed standard die when it is over taken by events.
Even 20 years ago the Internet was obviously not going to be able go on as before where you could make major changes over a long weekend during the summer at the few core university's that where the the internet.
That is why ipv6 should have been replaced.
Re: Whatever happened to the IPv4 address crisis?
#96This article is focused on the US, a country which was never really going to feel the brunt of the IPv4 crunch. For an example of a real victim, look at Qatar, a country which only has a single IP address for the entire country (everyone sits behind a NAT): https://en.wikinews.org/wiki/Qatari_proxy_IP_address_tempora... [0] Whenever someone from Qatar decides to vandalize Wikipedia, Wikipedia is forced (temporarily)…
I can assure you the US is feeling the brunt of the IPv4 crunch. I'm building something that needs massive amounts of public address space and I simply can't get IPv4 addresses for it. I've asked multiple providers. You are LUCKY if you can get a /28 at this point. Hoarding. Rolling with IPv6 instead. I get you have an interest in the Qatar/Wikipedia situation, but it seems to be unlikely due to IP address resource m…
I just went shopping for vendors at my San Francisco datacenter and had no problem replicating my current /26 + /27. Some vendors offered a /24, even.

Whereas an IP can't be trivially masked?
Most free proxies are already blocked on wikipedia. Finding more once yours have been block I don't think is very easy. Browser configurations can be easily generated by a computer and you never run out.
Does Wikipedia block editing from AWS IPs?

How could NAT work for an entire country of people behind one IP? My understanding was that NAT allows communication over separate ports, so for example a router with ip 123.45.67.89 can run three clients by sending their data over ports 50000, 50001 and 50002. How does this work when more than 65k people are trying to connect? There don't seem to be enough ports for that to be possible.
that limit only happens when 65k people try to use the same remote ip, otherwise the distinction can still be made for tcp streams.
Is there a minister of Port forwarding? What happens when I fire up chrome and Firefox with 80 pages each? Am I limited to a number out going connections? I assume the entire country is running off a Windows 95 box with two nics but that's just the way I imagine most cg-nat.

The SRV record is interesting -- basically extending DNS from a (name) -> (address) mapping to (name, service) -> (address, port) mapping
For whatever its drawbacks, IPv6 at least requires few application-layer changes. So I think it's a better solution to the problem than SRV records.

ARIN requires the demonstration of need before it allocates space. RIPE does not, it's just first come, first serve. I'm not sure about APNIC or LACNIC, and since AFRINIC is modeled heavily off of ARIN, I think they require need too, but things are so fucked over there I have no idea if that policy transferred.
ARIN requires justification as well. -- https://www.arin.net/policy/nrpm.html
Yeah, I said that, RIPE doesn't.
