Summary

Sappa

Sweden · AI-generated

residential isp sweden broadband

The AS handle SE-SAPPA is operated by Aktiebolaget Sappa, a Swedish broadband provider.

What it's used for

  • The address space carries residential customer traffic, evidenced by reverse DNS entries such as 213-204-215-254.clients.sappa.info and netnames like SAPPA-213-204-224_20-SOUTH.
  • With 25,088 IPv4 addresses announced across 20 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates an access network rather than a transit provider.

Notable

  • Registrants consistently identify as Aktiebolaget Sappa or AB Sappa, aligning with the AS holder; some prefixes use the netname BDTV-NET, reflecting historical branding or internal segmentation.
  • The inventory is finely subdivided into multiple /22 and /23 blocks, consistent with site-by-site segmentation of a regional ISP estate.
  • The operator has been present in routing tables since 2005, indicating a long-standing presence in the Swedish market.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
