RE: standards for giving out blocks of IP addresses

Hi Sheng,

Yes there is a formula,


"As many as they need to address their hosts/interfaces." If you look at the
arin website (www.arin.net) I believe you may find some guidelines.


Bandwidth shouldn't be the driving factor but specific addressing needs
should be.

"ISP" can mean so many things these days:)

If they have a 100 or so dial up ports and a dozen or so additional servers
and hosts then a /24 should be  more than enough.

With 2Mb of transit they are not going to be any bigger than that?
They may even get away with less addresses depending on what they're doing.

Hi, is there a standard or a practice on how much IP addresses an ISP should
provide to his/her client given that this client has bought only 2Mb of
bandwidth and this client is an ISP?
Thanks
sheng
