Residential RIPE Cable/DSL/ISP
Summary
Rekers Digitaltechnik
isp cable dsl germany
RDT is operated by Rekers Digitaltechnik GmbH & Co.KG.
What it's used for
- The address space carries residential and business internet access, identified by the netnames
DE-RDTONLINE-20190621andDE-RDTONLINE-20150612. - The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 95 observed neighbours; this ratio of limited address space against a high number of peering partners indicates a transit or upstream role rather than a large-scale access network.
- Traffic from this AS consists of subscriber internet access for cable and DSL customers in Germany, as the operator is identified as a Cable/DSL/ISP.
Notable
- Registrants for both announced IPv4 prefixes match the AS holder, Rekers Digitaltechnik Beteiligungsgesellschaft mbH trading as Rekers Digitaltechnik GmbH & Co.KG.
- The address inventory consists of two /22 blocks in the 45.89.168.0 and 185.104.160.0 ranges, along with a single /29 IPv6 prefix.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
