At $1000 per contract I do not care. I will retire and be happy.

Seriously ISPs are often valued by number of active contracts. A typical
value might be $100 to $200. The value of an IPv4 address can not go any
higher than this because at that point you can buy another company just to
get the addresses.

My customers have been demanding IPv6 for some time already.

They will have their free IPv6 and will care less about a non shared IPv4.
This will cause the valuation of IPv4 to crash at some point because the
demand will disappear.

RIPE gives you 1k addresses. This is not enough even for two guys and a
router. But yes it is a nice token.

The big companies have now gone without new space for a while. Just a few
months ago I bought 2k addresses at $6 per address. I do not observe any
rising tendency in IPv4 pricing.
