Summary

Corteva AgriScience

United States of America · AI-generated

business agriculture corporate

AS33625 is operated by Corteva AgriScience LLC.

What it's used for

  • The address space carries corporate infrastructure for an agricultural company, evidenced by netnames PHIBRED-B and registrant Pioneer Hi-Bred International, Inc.
  • With 1024 IPv4 addresses across 2 prefixes and only 3 observed neighbours, the low neighbour-to-address ratio indicates an internal corporate estate rather than a transit or access network.

Notable

  • Registrants Pioneer Hi-Bred International, Inc. align with the announcer Corteva AgriScience LLC, reflecting the corporate lineage of the space.
  • Corteva AgriScience was formed in 2017 through the spin-off of DowDuPont's agricultural division, which included Pioneer Hi-Bred International.
  • The inventory consists of two /23 blocks (170.54.198.0/23 and 170.54.206.0/23) 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: 436 networks and 1,771 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.
