AS13063 Gothenburg
Unclassified RIPE
Summary
SKF
enterprise business infrastructure
A full /16 behind one neighbour, with a handle that is just a city name.
What it's used for
- The network of a Swedish industrial manufacturer. 65,536 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The AS handle is recorded as
Gothenburg. - The entire inventory is
163.157.0.0/16, netnameSKFNET. - The registry lookup returned the netname but no registrant name.
- Three addresses were sampled and none returned a name.
Interesting
- The handle is a city and nothing more, the same collapse seen elsewhere in this range where a postal address replaced the name. Here it has gone one step further: not a street, not a company, just a place. As an identifier it is close to useless, and it has survived twenty-five years because nothing depends on it.
- A whole /16 announced through a single neighbour, with no name published for any address, is a corporate network that treats its allocation as private space that happens to be routable. The address count says nothing about how much of it is used.
- A missing registrant name on an actively announced /16 is a gap in the public record rather than in the network. Legacy allocations from before the current registration rules often carry incomplete objects, and there is no process that forces them to be filled in.

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 1,772 prefixes, as published 2026-10-15. 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.
