Summary

Adacor Hosting GmbH

Germany · AI-generated

hosting cloud kubernetes germany

The AS handle ADACOR-AS is held by Adacor Hosting GmbH.

What it's used for

  • The address space carries static IP infrastructure for a managed hosting and cloud services provider, evidenced by reverse DNS entries such as 130-0-73-0.static.ip.adacor.net and netnames like DE-ADACOR-20110304.
  • The AS announces 12,800 IPv4 addresses across 14 prefixes and 4 IPv6 prefixes, while maintaining only 3 observed routing neighbours, a ratio indicative of a hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints, Kubernetes clusters, and managed hosting services for digital agencies and enterprises, consistent with the operator's focus on Azure, Kubernetes, and cloud consulting.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing ADACOR Hosting GmbH, while specific blocks are registered to adesso as a service GmbH, Straylight GmbH, and Klett IT GmbH.
  • The address inventory is fragmented across multiple distinct netnames, including DE-ADACOR, DE-ADACOR-20110304, DE-ADACOR-20111014, DE-ADESSOHOSTING-20130222, DE-STRAYLIGHT-20130320, and K-NET-185-186-220_24, reflecting a diverse portfolio of acquired or leased address space.

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 1,782 prefixes, as published 2026-10-16. 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.
