Summary

United States of America · AI-generated

government education municipal

COLVA is the autonomous system for the City of Lynchburg, a municipal government in Virginia.

What it's used for

  • The address space carries municipal and educational infrastructure, evidenced by the netname CVGS-NET for the Central Virginia Governor's School and NTELO-206-248-244-0-COL for the City of Lynchburg.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained network typical of a local government or institutional site rather than a transit provider.

Notable

  • Registrants align with the announcer, listing both the Central Virginia Governor's School and the City of Lynchburg as holders of the respective prefixes.
  • The inventory consists of two /24 blocks, one dedicated to a specific school and the other to the city, reflecting a segmented internal estate for municipal services.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
