AS16364 SONY-DADC
Unclassified RIPE
Summary
Sony DADC Europe
enterprise media business
Three blocks, three netname conventions, and one of them jams the brand and a legal form into nineteen letters.
What it's used for
- A manufacturer's network. Three IPv4 prefixes announced from Austria, no IPv6, two thousand five hundred and sixty addresses, through two observed BGP neighbours.
Notable
- One netname is a country code, then the brand, a country name and a legal form run together without separators, then a full date. It names a national entity that the holder field does not.
- The second netname is the brand alone, no country code, no date, no suffix.
- The third is the brand and the word for a network, which the second did not think it needed.
- All three blocks are registered to the same company with the same administrators, so the three conventions describe one owner filling in one form three times.
- The administrators' label puts a space after the brand and hyphens through the rest, mixing both separators in one string.
- One of nine queried addresses answered: three letters, then a two-letter country label that is not the one these blocks are announced from, then the company's domain.
Interesting
- The netname on the newest block is the longest and the most specific, which is the opposite of how these things usually go. Someone decided the bare brand was ambiguous and overcorrected.
- A hostname carrying a country label from elsewhere is the tell that the machine is named for the office that owns it rather than the rack it sits in.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
