AS8

AS8 is a legacy single-digit allocation registered under ARIN to Rice University, and it remains a live campus network. It originates about 16 IPv4 prefixes and one IPv6 prefix (~463,000 IPv4 addresses), importing transit from AS2914 (NTT) and AS3356 (Level 3/Lumen) and peering at an exchange via AS4557. For triage this is a clean, long-established academic network: encountering it indicates Rice University campus space. The AS8 ↔ AS4557 pair both belong to Rice — AS8 is the legacy origin and AS4557 the busier peering ASN — so they should be cross-linked. The ARIN ASN RegDate of 1984-03-26 is one of the earliest in the registry (org RegDate 1983-12-02). The only technical hygiene note is a single RPKI-invalid IPv4 origin (remainder unknown). No notable public abuse signal was found as of June 2026.

Analyst note

Live single-digit university ASN; the AS8 ↔ AS4557 pair both belong to Rice (AS8 is the legacy origin, AS4557 the busier peering ASN). One IPv4-invalid ROA is the only hygiene flag.
