Hello Wilfred,

On Thursday January 06 2022 13:45, you wrote to me:

1) For IPv6 it is no issue. There is no shortage on IPv6 adresses. (yet)

2) 1% is too little for an overbooking system with a resonable margin for
fluctuations. You can't just use all those 10000 adresses elsewehere, you have
to leave a subsatnatial number on the shelve just in case a lot off those
off-liners decide to come on-line at the same time. I don't think it is worth
it with those margins.

3) They don't do it. It I go off-line my address remains reserved for me for
at least a week.

 WV> And it's probably easier to "administer" dynamic addresses.

Is it? With dynamic adresses they have to keep logs of who uses what address
(prefix) at what time. (For law enforcement purposes).


Cheers, Michiel
