AS7046 RFC2270-UUNET-CUSTOMER
Unclassified ARIN
Summary
Verizon Business (UUNET RFC 2270 customer AS)
enterprise legacy
RFC2270-UUNET-CUSTOMER is a shared autonomous system operated by UUNET, now part of Verizon Business. It is not one organisation's network: it is the AS number UUNET hands to customer sites that are single-homed to it, following the practice described in RFC 2270 ("Using a Dedicated AS Number for Sites Homed to a Single Provider").
What it's used for
- Originating the prefixes of many separate UUNET/Verizon customer networks that all sit behind the same upstream, so each does not need its own globally unique AS number.
- Several hundred IPv4 prefixes and a couple of dozen IPv6 prefixes are announced under it, adding up to roughly half a million addresses.
Notable
- Because the AS is shared, its address space belongs to unrelated end customers rather than to Verizon itself. Reverse DNS across it lands on a mix of enterprise, government and legacy carrier-customer names, with no single consistent pattern.
- Geolocating this AS as a whole is meaningless: the prefixes under it can be anywhere Verizon Business serves.
- The ASN was registered with ARIN in the mid-1990s, during UUNET's period as one of the dominant commercial internet backbones.

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 2026-10-11, 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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
