IP ranges in Denmark

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

Denmark in numbers

The 48 countries here hold 725,908,608 IPv4 addresses; Denmark has 12,007,968 in 1,519 blocks, 1.65% of the total, rank 14 of 48. The country just above it is Belgium with 12,234,880 addresses (1.69%), the one just below Austria with 11,181,664 addresses (1.54%). There are 1,519 blocks: 974 allocated (64.1%) and 545 assigned (35.9%). The oldest block was delegated in 1988 and the newest in 2026; 1989 is the year with the most new blocks. The largest share of the addresses, 7,923,232 of 12,007,968 (66.0%), came in the 2000s. The same RIPE file lists 410 IPv6 prefixes and 470 AS numbers for Denmark.

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 Denmark the registry is RIPE NCC, which publishes every day which address blocks it has delegated to which country. A block registered in Denmark 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: 1,519 blocks with 12,007,968 addresses. The largest block holds 524,288 addresses and starts at 87.48.0.0.

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 Denmark, sorted by first address:

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

ripencc|DK|ipv4|2.56.4.0|1024|20190313|allocated ripencc|DK|ipv4|2.59.180.0|1024|20190326|allocated ripencc|DK|ipv4|2.59.184.0|1024|20190326|allocated

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

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

1519

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

12007968

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 87.48.0.1

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