How many IP addresses does Luxembourg have?
Luxembourg holds 1,848,320 IPv4 addresses in 556 blocks and 109 IPv6 prefixes, the 77th largest IPv4 holding of 239 countries (0.05% of all allocated IPv4). Compare it with other countries on the IP ranges by country page.
Which networks use the most Luxembourg IP addresses?
European Commission (AS42848, 327.7K addresses), POST Luxembourg (AS6661, 219.9K addresses) and G-Core Labs S.A. (AS199524, 103.7K addresses). Look up any single address with the IP lookup tool.
How do I block all Luxembourg IP addresses?
Download the list above in the format of your firewall: iptables/ipset, nginx, Apache, ufw or MikroTik. Turn on "aggregate" to merge adjacent blocks into fewer rules. The raw list is at /Ranges/LU.txt, one CIDR per line. To inspect a single block use the CIDR calculator.
Who assigns IP addresses in Luxembourg?
RIPE NCC, the regional internet registry for Europe, the Middle East and Central Asia. ProxySpace downloads its delegation file every day; the most recent Luxembourg allocation in it is 2026-06-17.
Are there free proxies in Luxembourg?
Yes, 1 in the current lists. See free Luxembourg proxies for the lists per protocol, refreshed every 20 minutes.
