Unclassified ARIN Educational/Research
Summary
The University of Electro-Communications
education research university japan
UEC-EXP is operated by The University of Electro-Communications.
What it's used for
- The space carries the university's internal network, identified by the netname
UEC-NET-CIDR-BLK-JPregistered to the Japan Network Information Center. - The AS announces a single IPv4 prefix,
192.50.27.0/24, comprising 256 addresses, with no IPv6 prefixes in inventory. - With only 3 observed neighbours, the network functions as a small, self-contained endpoint for the university's academic and research activities rather than a transit or access provider.
Notable
- The registrant for the announced prefix is the Japan Network Information Center, which is consistent with the standard allocation process for Japanese educational institutions.
- The address inventory consists of a single contiguous /24 block, indicating a compact and straightforward network footprint.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
