Summary

State of Nevada

United States of America · AI-generated

government business internal

SILVERNET is operated by the State of Nevada.

What it's used for

  • The address space is registered under the netname NEVADA-STATE with registrants including State of Nevada, Nevada Abuse, Nevada IP Admin, and Nevada NOC, indicating a government-managed internal network.
  • The AS announces a single IPv4 prefix, 167.154.0.0/16, comprising 65536 addresses, with 0 IPv6 prefixes. It maintains 2 observed neighbours, a ratio consistent with a dedicated corporate or government estate rather than a transit or access provider.

Notable

  • The registrants in the RDAP data align directly with the AS holder, confirming the space is owned and administered by the State of Nevada.
  • The inventory consists of one contiguous /16 block, representing a finely subdivided internal corporate estate for state operations.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
