What it's used for

ip-45.84.41.0.f2x.nland netnames likeNL-F2X-20120628. - The AS announces 31,232 IPv4 addresses across 21 prefixes and 3 IPv6 prefixes, while maintaining 122 observed routing neighbours. This ratio of moderate address space to high peering count indicates a regional access provider purchasing transit and peering for customer connectivity.
- Traffic from this AS consists of subscriber eyeballs accessing the internet via fiber and DSL connections, as well as web and API endpoints for the provider's own infrastructure.

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.
