AS31673 Uniserver Internet B.V.ASN lookup: IP ranges, prefixes and network type
AS31673 is the autonomous system number (ASN) announced by Uniserver Internet B.V.. It announces 43 prefixes, 56,576 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 AS31673 means for detection
Registry data does not say what kind of network Uniserver Internet B.V. 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.
