Summary

isp business
Twenty announcements that add up to two /19s, under a netname dated March 1998.
What it's used for
- Fibre access in Sweden. 16,384 addresses in 20 IPv4 prefixes, one IPv6 prefix, and 29 observed BGP neighbours.
Notable
- Eight of the announcements tile
212.3.0.0/19exactly, in pieces from/24to/20. - Ten more cover
62.80.192.0/19apart from two single/24s, at62.80.203.0and62.80.205.0. - The netnames are
SE-LEISSNER-980312andSE-LEISSNER-20011012, registered to Leissner Data AB — a different name from the AS holder, Gotalandsnatet AB. - Sampled addresses answer
dynamic.cust254.27.ftth.gotanet.se,dynamic.cust254.6.ftth.gotanet.seandoxygen.webway.se. - The IPv6 announcement is
2a02:920::/32.
Interesting
- Announcing a
/19as eight separate pieces sends eight routes where one would carry the same traffic. Every router on the Internet stores all eight. Deaggregation on this scale is usually the residue of blocks that were once handled separately and never merged back, and it outlives whatever reason produced it. - The two missing
/24s in the second range are the more interesting half. A gap in an otherwise complete/19means those 512 addresses go somewhere else, and finding out where requires looking at whoever else announces them. 980312is the oldest netname date in this stretch of the number range, from a period when the two-digit year still had two years left to run.ftthin the reverse names is fibre to the home, andwebway.seis a third brand again.

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: 431 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.
