I'm aware of a company that had a /19. They sold a /20 for I think $40k
and kept the other half, and they still had more IP's than customers.
I think we're at or near a tipping point with IPv6. At some point in
the past having IPv6 was like being the only guy with a fax machine. At
this point something like 2/3's of the traffic hitting certain major
edge providers is IPv6. There are, of course, still places you can only
go with IPv4, but you can hit the heavy hitters like Google, Facebook,
and Netflix on v6.
If I was starting new today, I'd do dual stack. I'd get my /32 IPv6
block and then a IPv4 /24 from the transition pool. Everybody would get
a private CGNAT address and a public /56 prefix delegation. A /56 seems
absurdly huge for a home, but that's literally the recommended
practice. If someone had to have their own public v4 address my policy
would be that they have to pay extra for that.
....if I was starting fresh today that is. If you already are handing
out public v4 addresses and now you take them away then you'll have to
deal with a few restless natives who can't login to their NVR anymore or
whose XBox has "strict NAT" all of a sudden. You can tell them you sold
the IP addresses because you always wanted a new Corvette, or you can
give them a spiel about depletion and scarce resources. I'm not sure
either story will really go over well.

So today I looked over my kingdom and realized I'm sitting on $96,000
worth of IPv4 space. But, much like the stock market it's only worth
that if you sell it.
On the other hand, I'm using those IPs to run my business. At what
point does it make sense to sell them and just NAT everyone because
the money you get from the sale is a better business decision than
just sitting on them? Maybe keep a /24 or two.
Anyone here ever pondered this while they lay awake in bed?
