IP addresses allocated to Switzerland over time since 1993
Why the variance?
Recently I found BGP Expert site, which is a nice Internet routing reference. Once a month the site gathers a list of all the allocated IP addresses around the world from the respective authorities and dumps them into a database. The database is queryable via the Addresses Per Country page.
...the number of IP addresses used in every country of the world. The numbers are generated from information published by the Regional Internet Registries (AfriNIC, APNIC, ARIN, LACNIC and RIPE NCC) published on their FTP servers.
Using this query page, I saved the results of all years that Switzerland was listed, 1993 onwards. Here is a graph of the data with a trend line.
There is a lot more variance year-over-year than I would have expected. I have no idea why.
