Summary
Sohonet Limited
isp enterprise legacy
SOHONETEU-AS is Sohonet, a specialist network operator for the film, television and post-production industry. It was founded in 1995 by a group of London post-production houses in Soho, which is where the name comes from.
What it's used for
- The Sohonet Media Network: private, high-bandwidth connectivity between studios, post houses, VFX facilities and cloud providers, plus internet access for production sites and shoots.
- Customers are media and entertainment companies, so the address space sits behind editing suites, screening rooms and production offices rather than homes.
Notable
- This is a community-of-interest network. It exists to move large media files and review streams between a defined industry, not to sell general-purpose transit.
- Sohonet's footprint spans the UK and North America (Soho and Los Angeles being the two centres of gravity), which is unusual for an AS of this size.

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: 445 networks and 1,817 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.
