Hello Bj”rn,

 MR>> Phase 4 means that just /8 IPv4 addresses are still available.

 BF>    Surely you mean that only *one* /8 address space is available?

Yes, depletion is defined as when there is just one /8 left.

 BF>    After all, that's more than 16 million addresses, right?

2^^(32-8)=16777216 to be precise.

But the terminology is a bit misleading. The IPv4 adresses running out is not the same as the oil running out. when the oil is burned, it is gone. But the IP adresses are not "burned", all the adresses can still be used. You just can't get any new ones.

 BF>    And still, according to an article in a Swedish computer magazine,
 BF> less than 4% of all the ISPs in the world has gone full IPv6.

 BF>    So much for letting the "market" sort it all out...

Indeed....

I wonder when it will affect Fidonet. Mobile ISP's here have already resorted to CGNAT. You can forget running a fully fledged Fidonet node on a mobile device if you are not at home. You will not get a globally routeable IPv4 address when on the move. The best you can do is run a point.

It will be a matter of time until the fixed networks will do the same...


Cheers, Michiel
