Summary
TransitX
transit byoip hosting uk
TRANSITX is operated by TransitX Ltd.
What it's used for
- The address space carries IP blocks leased to various third-party entities, including Sky UK Limited (netname
SKY-LEASED-IPXO), Braveway LLC (US-BRAVEWAY-20190430), systea s.r.o. (CZ-SYSTEA-20180119), GigaTux Ltd (UK-GIGATUX-20190918), and 365 Group LLC (365GROUP). - The AS announces 34,560 IPv4 addresses across 121 prefixes with only 1 observed neighbour, indicating a transit or BYOIP (Bring Your Own IP) service model where TransitX provides routing for customer-owned space.
- Traffic consists of web and API endpoints for the diverse set of hosting and enterprise customers whose IP space is aggregated under this AS.
Notable
- Registrants vary significantly from the announcer, reflecting a portfolio of leased IP space from entities such as Sky, Braveway, and Micron Hosting.
- The inventory is fragmented into many small /23 and /24 prefixes, consistent with a BYOIP service aggregating disparate customer allocations.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
