Unclassified ARIN
Summary
Neill Corporation
business corporate retail us
NEILL-CORPORATION is the autonomous system for Neill Corporation, a US-based beauty supply and education company.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by reverse DNS entries such as
21-subnet.neill.netandinternal-bcaddr.neill.net. - The AS announces 1792 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a small, isolated corporate estate rather than a transit or access network.
Notable
- Registrants are consistent with the announcer, listing "Worldcom/Neill Corporation" for the largest block and "Neill Corporation" for the others.
- The inventory consists of three distinct IPv4 blocks: 208.245.20.0/22, 208.64.208.0/23, and 208.64.215.0/24, with no IPv6 prefixes announced.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
