Costa Rica: IP addresses and networks
Costa Rica holds 2,334,976 public IPv4 addresses — 0.063% of all allocated IPv4 space, which ranks it #69 worldwide. Its address space is administered by LACNIC.
It also holds enough IPv6 to cover 6,623,311 end-site networks, a figure that says more about how recently its providers deployed IPv6 than about how many people live there.
126 autonomous system numbers are registered there, and 81 of them currently announce routes on the public internet.

Allocation reflects when a country's networks joined the internet rather than its population, and addresses registered here can be routed anywhere in the world. That is one of the reasons IP geolocation is an estimate rather than a fact.
