AS17687 National University Corporation Nagoya UniversityASN lookup: IP ranges, prefixes and network type
AS17687 is the autonomous system number (ASN) announced by National University Corporation Nagoya University. It announces 3 prefixes, 131,328 IPv4 addresses in total. Every address inside those ranges is routed by this operator, which is what makes the number the shortest answer to who runs a given address.
Directory data is unavailable at the moment, so the prefix list and the range membership counts are missing from this page. What you can see comes from the committed snapshot and is accurate as far as it goes. Try again shortly.

What AS17687 means for detection
Registry data does not say what kind of network National University Corporation Nagoya University runs, and this page will not guess. Ownership alone cannot settle it: the name is the only clue an ASN carries about purpose, and this one carries none. A single address on it can still be classified, because that uses behaviour and range membership rather than the operator's name. Run one below and see what comes back.
The verdict for a single address is never settled by the ASN alone. It is the starting point, and IP Detection adds range membership, behaviour and history on top of it before it answers.
