IP ranges in Italy

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

Italy in numbers

The 48 countries here hold 725,908,608 IPv4 addresses; Italy has 54,015,104 in 3,718 blocks, 7.44% of the total, rank 4 of 48. The country just above it is France with 81,555,536 addresses (11.2%), the one just below the Netherlands with 47,902,752 addresses (6.60%). There are 3,718 blocks: 3,290 allocated (88.5%) and 428 assigned (11.5%). 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, 30,049,088 of 54,015,104 (55.6%), came in the 2000s. The same RIPE file lists 1,065 IPv6 prefixes and 1,319 AS numbers for Italy.

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 Italy the registry is RIPE NCC, which publishes every day which address blocks it has delegated to which country. A block registered in Italy 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: 3,718 blocks with 54,015,104 addresses. The largest block holds 5,046,272 addresses and starts at 151.3.0.0.

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 Italy, sorted by first address:

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

ripencc|IT|ipv4|2.32.0.0|1048576|20100429|allocated ripencc|IT|ipv4|2.56.92.0|1024|20190313|allocated ripencc|IT|ipv4|2.56.128.0|512|20190314|allocated

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

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

3718

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

54015104

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 151.3.0.1
