@feld @RandomDamage @mathaetaes early 2000s in my case. Worked at a hosting provider with around 7k individual websites hosted (around half being e-commerces), and I remember spending a week polishing a "petition" to RIPE to grant us some IPs and the screams of joy when we received a /24 share (from /21 or /22 requested, don't recall now) up from the /27 range we were squeezing in previously.
