Summary
POST Luxembourg
isp residential eyeball fiber dsl backbone
POST Luxembourg (EPT-LU) is the national incumbent telecom of Luxembourg, providing home broadband, mobile and postal services.
What it's used for
- Residential broadband for homes across Luxembourg: FTTH fibre and DSL, plus the national backbone and mobile network.
Notable
- An "eyeball" network: addresses here are Luxembourg home connections, not servers.
- As the state-owned incumbent, POST is the dominant fixed and mobile provider in the country and runs Luxembourg's primary telecom backbone.
Interesting
- Luxembourg is among Europe's most fibre-covered markets, and POST's small national footprint reaches nearly the entire population.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
