Summary

PR Newswire

United States of America · AI-generated

business media press corporate

PR-NEWSWIRE-USA-1 is operated by PR Newswire.

What it's used for

  • The address space carries corporate infrastructure for a global press release distribution service, evidenced by netnames like PRNEWSWIRE2 and NETBLK-PRNEWSWIRE, and reverse DNS entries pointing to vocuspr.com and bulletinhealthcare.com.
  • The AS announces 2816 IPv4 addresses across 9 prefixes with 4 observed neighbours, a ratio consistent with a business network maintaining direct peering or transit relationships for its distribution platform.

Notable

  • Registrants are consistent with the announcer, listing PR Newswire and PR Newswire Association LLC for most blocks, though one prefix (206.155.72.0/24) is registered to CenturyLink Communications, LLC under the netname CENTURYLINK-LEGACY-SAVVIS-BLK122.
  • The inventory consists of a mix of /23 and /24 blocks, including legacy space from Savvis and CenturyLink, indicating a history of acquisitions or address space consolidation.

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 1,783 prefixes, as published 2026-10-20. 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.
