Summary

Sun Chemical Corporation

United States of America · AI-generated

business corporate manufacturing

SUN-CHEMICAL is operated by Sun Chemical Corporation.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames SUNC-DC1 and SUNCHEM-NET registered to Sun Chemical Corporation.
  • The AS announces 1792 IPv4 addresses across 5 prefixes with only 4 observed neighbours, a ratio indicating a small internal corporate estate rather than a transit or access network.

Notable

  • Registrants are mixed: three prefixes are registered to Sun Chemical Corporation, while 63.115.115.0/24 and 192.195.212.0/24 are registered to Glencom, Inc. and Glencom Systems Inc. respectively, suggesting leased or historical space.
  • The inventory consists of five distinct IPv4 prefixes with no IPv6 announcements, reflecting a segmented internal network structure.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
