Reputation · trust score
A transparent 0–100 signal. Every entity starts at a neutral baseline of 65; threat-intel blocklists, exposure, reverse-DNS, routing and allocation each adjust it up or down. Higher is more trustworthy.
- Baseline (neutral) 65
- Multiple-origin (MOAS) routing anomaly −12
- Academic allocation +6

About Rice University
William Marsh Rice University, also known as Rice University, is a private research university in Houston, Texas, United States. Established in 1912, it spans 300 acres.
⚠ 2 MOAS prefixes — multiple origin ASNs detected
All MOAS anomalies →A previously stable prefix originated by AS8 is now also announced by another ASN (MOAS — Multiple-Origin AS), detected from our RIPE RIS collectors. Often benign (anycast, multi-homing, or a recent transfer) — but it can signal a route leak or prefix hijack, so it's worth inspecting.

How many IP addresses does AS8 announce?
AS8 announces 462.6K IPv4 addresses distributed across 16 routed CIDR prefixes. The network is registered in United States.
Who operates AS8?
AS8 is operated by Rice University. The organization is based in United States. You can view all IP ranges and related ASNs on the organization page.
What country is AS8 registered in?
AS8 is registered in United States. This indicates where the network operator is headquartered, though the IP addresses it announces may serve users globally.
