isp residential cable dsl

The AS handle WEMACOM is held by WEMACOM Telekommunikation GmbH.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS records pointing to subs.wemacom.net and registrant netnames such as DE-WEMACOM-20031009 and DE-WEMACOM-960214.
  • The network announces 34,304 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining 142 observed neighbours, a ratio consistent with an access network providing connectivity to end-users.
  • As a telecommunications company based in Schwerin, Germany, the traffic consists of subscriber eyeballs for cable and DSL internet services.

Notable

  • All registrants for the announced prefixes are WEMACOM Telekommunikation GmbH, aligning perfectly with the AS holder.
  • WEMACOM was founded in 1997 as a subsidiary of WEMAG AG.
  • The inventory includes a mix of prefix sizes, ranging from a /18 to a /23, all registered under the WEMACOM ISP role.

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: 442 networks and 1,771 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.
