About this network

FORTIS-AS is operated by Baykov Ilya Sergeevich.

What it's used for

• The address space carries hosting and residential infrastructure, evidenced by netnames such as BG-NETERRAIP-20180612 (Neterra Ltd.), RU-MAINACC-20190807 (ONER INVESTMENTS NOC TEAM), and RU-VPSVILLE1-19880518 (LLC Vpsville).
• The AS announces 53,504 IPv4 addresses across 144 prefixes and 1 IPv6 prefix, with 11 observed neighbours; this ratio of high address volume to low peering count indicates an access or hosting network rather than a transit provider.
• Traffic from this AS consists of web hosting endpoints, VPS instances, and residential subscriber connections, consistent with the operator's classification as a hosting service provider.

Notable

• Registrants include Neterra Ltd., ONER INVESTMENTS NOC TEAM, DGTL TECH UK LLP, LLC Vpsville, and Abuse-C Role, indicating a diverse portfolio of leased or managed IP blocks rather than a single corporate estate.
• The inventory is fragmented across multiple /22 and /23 blocks from various RIRs, including RIPE and ARIN, reflecting historical acquisitions or leasing of address space.
