Summary

School of Visual Arts

United States of America · AI-generated

education business private

The AS handle SVA-ANS is held by School of Visual Arts, Inc.

What it's used for

  • The address space carries the internal network of the School of Visual Arts, a private non-profit art and design institution in New York City, as indicated by the netname SVA-15 and registrant School Of Visual Arts, Inc.
  • The AS announces 512 IPv4 addresses across 1 prefix (204.147.202.0/23) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant School Of Visual Arts, Inc. matches the registry holder and the AS handle, confirming direct ownership of the address space.
  • The inventory consists of a single /23 block, representing a compact and finely subdivided internal corporate estate typical of a university campus network.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
