IP ranges in San Marino

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

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 San Marino the registry is RIPE NCC, which publishes every day which address blocks it has delegated to which country. A block registered in San Marino 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: 25 blocks with 40,960 addresses. The largest block holds 8,192 addresses and starts at 89.186.32.0.

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 San Marino, sorted by first address:

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

ripencc|SM|ipv4|5.183.163.0|256|20250114|allocated ripencc|SM|ipv4|31.193.32.0|2048|20110426|allocated ripencc|SM|ipv4|45.65.80.0|1024|20181113|allocated

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

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

25

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

40960

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 89.186.32.1

All IPv4 blocks in San Marino

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