AS63771 BGPNAP - Border Gateway Protocol Network Analysis Project
Unclassified APNIC Educational/Research
Summary
BGPNAP
research education bgp analysis
BGPNAP is operated by the Border Gateway Protocol Network Analysis Project.
What it's used for
- The address space carries research infrastructure, evidenced by the netname
BGPNAP-CIDR-BLK-JPand reverse DNS entries like103-96-65-0.bb1.bgp.ad.jp. - The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale research or educational network rather than a transit provider.
- Traffic from this AS consists of BGP network analysis tools and research endpoints, as the organization is a voluntary group of engineers focused on BGP network analysis.
Notable
- Registrants for both IPv4 prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which aligns with the announcer's identity as a Japanese research project.
- The address inventory is compact, consisting of two /22 IPv4 blocks and one /32 IPv6 prefix, typical for a specialized research initiative.

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 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
