Summary

DECHEMA

Germany · AI-generated

business non-profit scientific germany

The AS handle DECHEMA is held by DECHEMA Gesellschaft fuer Chemische Technik und Biotechnologie e V.

What it's used for

  • The address space carries the internal network of a non-profit scientific society, identified by the netname DECHEMA-NET and registrant DECHEMA Gesellschaft fuer Chemische Technik und Biotechnologie e V.
  • The AS announces 512 IPv4 addresses across 1 prefix (193.110.178.0/23) with 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and research staff accessing the internet, as DECHEMA is a German non-profit society for chemical engineering and biotechnology based in Frankfurt am Main.

Notable

  • The registrants align with the announcer, listing Interactive Network Communcations GmbH as the account role and DECHEMA Gesellschaft fuer Chemische Technik und Biotechnologie e V as the primary registrant and abuse contact.
  • The address inventory consists of a single contiguous /23 block, typical for a single-site corporate network.

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 1,783 prefixes, as published 2026-10-17. 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.
