Summary
Luxembourg Amateur Radio Union
research infrastructure telecom
A volunteer radio society announcing part of the range set aside for amateur packet networks.
What it's used for
- An amateur radio association's network. One IPv4
/21and three IPv6 prefixes announced from Luxembourg, two thousand and forty-eight addresses, through a single observed BGP neighbour.
Notable
- The IPv4 block sits inside the range reserved decades ago for amateur radio digital networks, and its netname is that range's own name.
- The registrant is not the announcing society but the foundation that administers the whole range on behalf of operators everywhere.
- The three IPv6 prefixes are a
/44and two/43s from one allocation, so the association has far more IPv6 space than IPv4. - The routing archive first saw this number more than a decade after the numbers around it.
- The holder's legal form is the abbreviation for a non-profit association, written with full stops.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The amateur range is the oldest surviving example of address space held in common. It was set aside for hobbyists before addresses were scarce, is administered by a foundation rather than a company, and pieces of it are lent to national societies who route them themselves.
- One neighbour and two thousand addresses is what a hobby network looks like from outside: a single connection to the rest of the internet, kept up by volunteers.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
