business media captioning corporate

VITAC is the autonomous system for VITAC Corporation, a US-based audio transcription and captioning provider.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname VITAC-PUBLIC-ADDRESS-SPACE and the registrant VITAC Corporation.
  • The AS announces a single IPv4 prefix, 204.239.124.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the routing footprint indicates a small, self-contained corporate network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant VITAC Corporation matches the registry holder and the AS handle, confirming consistent ownership.
  • VITAC has been part of the Verbit family since 2021, acting as the company’s media arm for broadcasters and media organizations.
  • The address inventory consists of a single /24 block, which is typical for a small business or internal corporate estate.

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 1,784 prefixes, as published 2026-10-19. 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.
