IP ranges in Finland

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

Finland in numbers

The 48 countries here hold 725,908,608 IPv4 addresses; Finland has 13,859,392 in 1,093 blocks, 1.91% of the total, rank 12 of 48. The country just above it is Norway with 15,528,464 addresses (2.14%), the one just below Belgium with 12,234,880 addresses (1.69%). There are 1,093 blocks: 781 allocated (71.5%) and 312 assigned (28.5%). 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, 6,160,128 of 13,859,392 (44.4%), came in the 2000s. The same RIPE file lists 312 IPv6 prefixes and 365 AS numbers for Finland.

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 Finland the registry is RIPE NCC, which publishes every day which address blocks it has delegated to which country. A block registered in Finland 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: 1,093 blocks with 13,859,392 addresses. The largest block holds 524,288 addresses and starts at 91.152.0.0.

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 Finland, sorted by first address:

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

ripencc|FI|ipv4|2.58.88.0|1024|20190321|allocated ripencc|FI|ipv4|2.58.220.0|1024|20190322|allocated ripencc|FI|ipv4|5.22.208.0|4096|20120504|allocated

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

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

1093

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

13859392

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 91.152.0.1

All IPv4 blocks in Finland

From the RIPE file of 2026-10-29, sorted by address. The last address is the first one plus the size minus one.
