IP ranges in Sweden

This page lists the IPv4 address blocks registered to organisations in Sweden and checks single addresses. The basics of IP addresses, masks and subnets are in Networks; the other countries are in IP ranges by country.

Sweden in numbers

The 48 countries here hold 725,908,608 IPv4 addresses; Sweden has 31,417,888 in 2,111 blocks, 4.33% of the total, rank 7 of 48. The country just above it is Spain with 31,944,832 addresses (4.40%), the one just below Switzerland with 23,277,424 addresses (3.21%). There are 2,111 blocks: 1,483 allocated (70.3%) and 628 assigned (29.7%). The oldest block was delegated in 1984 and the newest in 2026; 2019 is the year with the most new blocks. The largest share of the addresses, 17,279,584 of 31,417,888 (55.0%), came in the 2000s. The same RIPE file lists 855 IPv6 prefixes and 862 AS numbers for Sweden.

Check an IP address

Type an IPv4 address. The answer comes from the Sypex Geo database on this server; like every geolocation database it can be wrong, especially about the city.

Where the list comes from

IP addresses are handed out by five regional internet registries. For Sweden the registry is RIPE NCC, which publishes every day which address blocks it has delegated to which country. A block registered in Sweden is usually used there, but not always: a company may use its addresses abroad, and a VPN makes any visitor look like someone else.

The table below is the RIPE file of 2026-10-29: 2,111 blocks with 31,417,888 addresses. The largest block holds 1,048,576 addresses and starts at 78.64.0.0.

Get the list yourself

Download the statistics file of RIPE NCC:

curl -s -O https://ftp.ripe.net/pub/stats/ripencc/delegated-ripencc-latest

The first line says when it was made; the sixth field is the date:

head -1 delegated-ripencc-latest

2|ripencc|1793314799|167770|19700101|20261029|+0100

Each later line is one block: registry, country, type, first address, number of addresses, date and status. The IPv4 blocks of Sweden, sorted by first address:

awk -F'|' '$2=="SE" && $3=="ipv4"' delegated-ripencc-latest | sort -t'|' -k1,1V | head -3

ripencc|SE|ipv4|2.0.0.0|131072|20100712|allocated ripencc|SE|ipv4|2.2.0.0|65536|20100712|allocated ripencc|SE|ipv4|2.56.28.0|1024|20190313|allocated

How many blocks, and how many addresses they hold together:

awk -F'|' '$2=="SE" && $3=="ipv4"' delegated-ripencc-latest | wc -l

2111

awk -F'|' '$2=="SE" && $3=="ipv4" {s+=$5} END {print s}' delegated-ripencc-latest

31417888

allocated means RIPE gave the block to a provider (a LIR) to hand out further; assigned means it went to an end user directly.

Who owns a block

The statistics name no owners. The RIPE database does: ask it with whois for any address of a block, and look at the lines netname, descr and org:

whois 78.64.0.1
