Be told before you find out the hard way
One message on any day something moves under ORG-TMHB2-RIPE — a customer arriving, a customer leaving, a sponsorship ending.
RIPE publishes only the current database and no dated archive, so this is not something you can look up later — it is only knowable if somebody was watching. Free, no account, and a way out in every message.
I am Tropynin Oleg, ORG-TO334-RIPE — another RIPE member, with my own autonomous system AS41800. If you hold one of the resources above and are weighing a move, tell me what you have and I will send a price.
