Summary
RFT Kabel Brandenburg
cable residential regional isp
The AS handle RFT-BRANDENBURG is held by RFT Kabel Brandenburg GmbH.
What it's used for
- The address space carries residential cable and DSL traffic, evidenced by reverse DNS entries such as
cpe-5054C40.ip-pool.rftonline.netand4d4ea400.ip-pool.rftonline.net. - With 28,928 IPv4 addresses announced across 13 prefixes and 117 observed neighbours, the network functions as a regional access provider rather than a transit hub.
Notable
- Registrants include both RFT Kabel Brandenburg GmbH and RFT Kabel Nord GmbH, with netnames like
DE-BKG-NEURUPPIN-20010814andRFT-NORD-20140120indicating shared or inherited infrastructure. - The address inventory is finely subdivided into multiple /21 and /22 blocks, reflecting site-by-site segmentation typical of a regional cable operator.

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.
