Summary

Mediaocean

United States of America · AI-generated

adtech business software

The AS handle MEDIAOCEAN is held by Mediaocean LLC.

What it's used for

  • The address space carries infrastructure for an advertising technology company, with all registrants identified as Mediaocean LLC and netnames set to MO-IPV4.
  • The AS announces 4352 IPv4 addresses across 12 prefixes and 8 IPv6 prefixes, while maintaining only 5 observed neighbours, indicating a business network with limited peering rather than a transit provider.

Notable

  • All registrants in the RDAP data agree with the announcer, consistently listing Mediaocean LLC for every prefix.
  • The address inventory is finely subdivided into multiple /24 and /23 blocks within the 168.238.0.0/16 space, reflecting internal corporate segmentation rather than a large access 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
