IP ranges in Bulgaria

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

Bulgaria in numbers

The 48 countries here hold 725,908,608 IPv4 addresses; Bulgaria has 4,341,824 in 1,833 blocks, 0.598% of the total, rank 23 of 48. The country just above it is Greece with 5,722,240 addresses (0.788%), the one just below Lithuania with 4,112,384 addresses (0.567%). There are 1,833 blocks: 1,587 allocated (86.6%) and 246 assigned (13.4%). The oldest block was delegated in 1990 and the newest in 2026; 2008 is the year with the most new blocks. The largest share of the addresses, 2,921,472 of 4,341,824 (67.3%), came in the 2000s. The same RIPE file lists 266 IPv6 prefixes and 751 AS numbers for Bulgaria.

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 Bulgaria the registry is RIPE NCC, which publishes every day which address blocks it has delegated to which country. A block registered in Bulgaria 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: 1,833 blocks with 4,341,824 addresses. The largest block holds 131,072 addresses and starts at 95.42.0.0.

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 Bulgaria, sorted by first address:

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

ripencc|BG|ipv4|2.56.12.0|1024|20190313|allocated ripencc|BG|ipv4|2.56.52.0|1024|20190313|allocated ripencc|BG|ipv4|2.58.92.0|256|20190321|allocated

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

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

1833

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

4341824

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 95.42.0.1
