> You've not been an ISP for too long.  Charging for IP space (even justified, not being used for spamming) is pretty common.  I don't get involved in sales very often, so I don't know what we charge for them, but I know we do.  I don't believe our rates for IPs have changed [yet] in anticipation of IPv4 runout.  Our standard IPv4 assignment for dedi/colo single servers has been /28.  For cloud, it's /32.  Anything more adds to the MRC.  I can see the former shrinking soon to /29 or /30 unless the customer demands more.

Sorry, hasty note.

Whenever someone says "how much can I charge for giving a customer more space than they need", I think "spammer".  Maybe that's wrong, maybe not, but that's the bell that rang in my head.  And I do hope that spammers will have their space reclaimed, because it is _not_ a justified use of space to put a /16 on a single mail server to avoid blacklists.

As for your first sentence, it is true, I Am Not An Isp. :)  However, I do get space from providers, and it is not at all normal for the provider to ask us for money.  But then, maybe we are special.
