Residential RIPE
Summary
kabelplus GmbH (formerly B.net / Wellcom)
isp cable legacy
WELLCOM is held by kabelplus GmbH, a subsidiary of the Austrian utility EVN AG and the largest cable and multimedia operator in Lower Austria and Burgenland. The handle preserves an absorbed brand: kabelplus was formed in 2012 out of the merger of kabelsignal and B.net, and the Wellcom name it once traded under is still the AS's registry label.
What it's used for
Consumer broadband over cable and fibre. The reverse DNS on the announced 141.98.176.0/22 is explicit about it: h141.98.176.001.dyn.cm.kabsi.at and h141.98.176.100.dyn.cm.kabsi.at — dyn for dynamic assignment, cm for cable modem, under kabsi.at, the operator's long-running ISP domain (from the old Kabsi / kabelsignal brand). Those are subscriber addresses, one hostname generated per IP.
Only about 1,024 addresses appear under this origin, with a single observed BGP neighbour. The group's main network is the neighbouring AS8339 (KABSI-AS), also kabelplus; this AS carries a small slice of the same eyeball estate.
Notable
- Two kabelplus ASNs, two absorbed brands:
KABSI-AS(AS8339) from kabelsignal andWELLCOM(AS8559) from B.net/Wellcom. Both are the same company today. - The
dyn.cmlabel is a rare case of rDNS naming both the assignment method and the access technology, which makes the residential call unusually clean.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
