About this network

THREE-A-HUB is operated by Three A Hub EOOD.

What it's used for

• The address space carries residential and business access traffic, evidenced by netnames such as BG-TAH-20160817, Three-A-Hub, and TAH-LAN3 registered to Three A Hub EOOD, alongside legacy blocks from Global Communication Net Plc and LanmaxNetOOD.
• The AS announces 2816 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, with 6 observed routing neighbours; this ratio of address space to peering partners indicates an access network rather than a transit provider.
• Traffic from this AS consists of subscriber eyeballs for cable and DSL services in Bulgaria, as the operator is identified as a Cable/DSL/ISP.

Notable

• Registrants are mixed, including Three A Hub EOOD, Global Communication Net Plc, and LanmaxNetOOD, suggesting the AS aggregates space from multiple entities or reflects historical acquisitions.
• The inventory includes prefixes originally registered to Global Communication Net Plc (e.g., BG-GCN-20090827, TARGOVISHTEGCN) and LanmaxNetOOD, indicating a consolidation of Bulgarian ISP infrastructure under the Three A Hub handle.
• The address inventory is fragmented across multiple /23 and /24 blocks, consistent with an organic growth pattern typical of regional ISPs.
