Summary

Meiji Gakuin University

Japan · AI-generated

education university japan

The AS handle MAIN is held by Meiji Gakuin University.

What it's used for

  • The space carries the university's internal network, identified by the netname MAIN-CIDR-BLK-JP and the registrant Japan Network Information Center; IRT-JPNIC-JP.
  • The AS announces 8192 IPv4 addresses within a single prefix (202.13.128.0/19) and maintains 1 observed neighbour, a ratio consistent with an isolated educational institution rather than a transit provider.
  • Traffic from this AS consists of student and faculty access, administrative systems, and campus services for a private Christian university with campuses in Tokyo and Yokohama.

Notable

  • The registrant Japan Network Information Center; IRT-JPNIC-JP aligns with the announcer, Meiji Gakuin University, as the space is allocated via the national registry.
  • The address inventory consists of a single /19 block, providing a contiguous range for the university's on-premises infrastructure.

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 1,852 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.
