Summary
Bolignet
residential fiber isp denmark
BOLIGNET-AS is operated by Bolignet A/S.
What it's used for
- The address space carries residential fiber internet traffic, evidenced by reverse DNS entries such as
217.71.4.0.dynamic.prod.bolignet.dkand217.71.7.255.notinuse.bolignet.dk. - The AS announces 8192 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 48 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a transit or peering-heavy role for a regional ISP.
- Traffic from this AS consists of subscriber eyeballs for Danish housing associations, providing 1000/1000 Mbit fiber internet connections to residential customers.
Notable
- Registrants for both announced prefixes (
DK-BOLIGNET-20071116andDK-BOLIGNET-20071021) are listed asBolignet LIR; BOLIGNET A/S, which aligns directly with the AS holder. - The address inventory consists of two /20 blocks in the 79.142.224.0 and 217.71.0.0 ranges, representing a compact and focused residential estate.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
