Summary

Nagarro ES GmbH

Germany · AI-generated

business it-services germany

ALLGEIERMS-AS is held by Nagarro ES GmbH.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by the registrant Nagarro ES Hostmaster and netnames DE-ALLGEIERMS-20100119 and DE-ALLGEIERMS-20190809.
  • The AS announces 3072 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal IT endpoints for Nagarro ES, a German IT full-service provider specializing in complex business applications and ERP landscapes.

Notable

  • Registrants for both announced prefixes agree with the announcer, listing Nagarro ES Hostmaster and Nagarro ES GmbH.
  • The operator was formerly known as Allgeier SE, which became Nagarro SE in 2020; the AS handle ALLGEIERMS-AS retains the legacy name.
  • The inventory consists of two distinct IPv4 blocks: 109.234.184.0/21 and 45.139.148.0/22, with no IPv6 prefixes announced.

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.
