Summary

Schaeffler Technologies AG & Co. KG

Germany · AI-generated

business automotive manufacturing corporate

AS20561-INA is held by Schaeffler Technologies AG & Co. KG.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname HP-INAWSKG and registrant Schaeffler Technologies AG & Co. KG across all announced IPv4 prefixes.
  • The AS announces 57,344 IPv4 addresses and 34 IPv6 prefixes, with only 2 observed neighbours, indicating a private corporate network rather than a transit or access provider.

Notable

  • All registrants for the announced prefixes (159.51.128.0/17, 159.51.64.0/18, 159.51.32.0/19) match the AS holder, confirming direct ownership.
  • The address inventory consists of three contiguous IPv4 blocks within the 159.51.0.0/16 range and a single large IPv6 allocation 2a03:85c0::/40 with multiple sub-allocations, typical of a large industrial enterprise.

Reputation

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 1,773 prefixes, as published 2026-10-13. 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.
