Summary
S3 Company Ltd
hosting legacy
Autonomous System 4849 (S3Company) is held by S3 Company Ltd, a Bulgarian hosting and data-centre operator based in Sofia, which runs its own facility and sells servers, colocation and IP connectivity.
What it's used for
- Hosting: dedicated and virtual servers, colocation, and the IP transit that goes with them, served out of the company's Sofia data centre.
- The network peers at the Bulgarian and regional exchanges and buys transit from several tier-1 and large international carriers.
Notable
- A hosting network. Addresses here are servers rather than end users, which is the relevant fact when this AS shows up in traffic or abuse data.
- The number is not where it started. Registration for AS4849 now sits in the RIPE region with a Bulgarian maintainer, having previously been an APNIC object in the Asia-Pacific region. Stale databases still show the old Hong Kong holder, so a low four-digit number here carries no early-internet pedigree, only a transfer history.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,773 prefixes, as published 2026-10-13. 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.
