Where AS11816 ranks
Countries where this operator is among the twelve largest by IPv4 address space, and its position there. An operator active in a country but outside its top twelve does not appear — so this is a list of where AS11816 is significant, not everywhere it has a presence.
| Country | IPv4 addresses | Rank there |
|---|---|---|
| Aruba | 134K | #1 |
| Caribbean Netherlands | 512 | #5 |
IPv4 only, counted where the address space is observed rather than where a registry allocated it, and limited to each country's twelve largest operators.
What an AS number is
An Autonomous System is a network under one routing policy — an ISP, a hosting provider, a large company. The AS number identifies it globally, and BGP uses it to work out how traffic reaches the addresses that network announces.
When a lookup tells you an address belongs to AS11816, it is telling you which organisation announces the route to it. That is usually a better answer to “who is this?” than the city on the map, because routing is a fact while geolocation is an inference.
Doing this for thousands of addresses?
These calculators run in your browser and never send us your input. When you need geolocation, ASN and network data for addresses in bulk, the API answers in one call — no key required to try it.
