Unclassified ARIN
Summary
HeadFirst Communications
enterprise legacy
HFCOMM-AS-01 belongs to HeadFirst Communications, a very small network operator registered in ARIN to an address in Waterville, Minnesota. It is a single-prefix, single-upstream network, and the public evidence is too thin to say confidently what the space carries.
What it's used for
Unclear, and the card says so rather than guessing. RIS sees one IPv4 prefix, 23.167.88.0/24 (256 addresses), one IPv6 /40, and exactly one observed neighbour. A single neighbour means the AS buys transit from one upstream and sells none: this is an end network, not a carrier. The /24 is registered in ARIN to HeadFirst Communications itself, so the space is self-held rather than leased in from a third party, which rules out the IP-brokerage shape.
Notable
- ARIN dates the AS number to November 2023. Despite the low five-digit number, this is recently reissued space, and nothing about the network is an early-internet artifact. The registration contact is an individual, and the postal address is a rural one, which is the profile of an owner-operator rather than a corporate NOC.
- The IPv6 allocation is notably generous relative to the IPv4 footprint: a
/40is enough to hand a/48to thousands of downstream sites. That is the shape an operator adopts when it intends to delegate to customers, but intent is not evidence, and no reverse DNS was observed on the addresses sampled to confirm what actually lives there. Held at low confidence for that reason.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
