The AS handle ASCOMFLEX is held by Comflex Networks ApS.
What it's used for
- The address space carries residential and business internet services, as indicated by the PeeringDB classification of "Cable/DSL/ISP" and the registrant netnames
DK-COMFLEX-20070724,DK-COMFLEX-20190725, andDK-COMFLEX-NET195. - The network announces 5632 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 1 observed neighbour in RIS. This high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.
Notable
- All RDAP registrants for the announced prefixes are consistent with the announcer, listing "Comflex Networks ApS" or "Comflex Networks NOC" as the responsible parties.
- The address inventory consists of three distinct IPv4 blocks: a /20, a /22, and a /23, all located in Denmark.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
