Unclassified RIPE
Summary
Region Stockholm
government healthcare enterprise
SLL Region Stockholm is operated by Region Stockholm, the regional government authority for the Stockholm region in Sweden.
What it's used for
- The address space carries internal corporate and public sector infrastructure, evidenced by netnames such as
SLL,SLLLAN-NET1, andSLLLAN-NET2registered to Region Stockholm. - The AS announces 203,008 IPv4 addresses across 14 prefixes and 1 IPv6 prefix, with 16 observed neighbours. This ratio of a large, finely subdivided address inventory against a moderate number of peering partners indicates an internal corporate estate with site-by-site segmentation rather than a transit or access network.
Notable
- Registrants largely align with the announcer, with most prefixes registered to "Region stockholm" or "Region Stockholm"; one prefix (192.36.202.0/23) is registered to Resilans AB under the netname
SE-RESILANS-20000317. - The address inventory consists of three large /16 blocks and numerous smaller /23 and /24 blocks, reflecting a structured internal network design typical of a large public sector organization.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
