AS199221 — TBG-NET-AS TBG OOD

AS199221 announces 6 IPv4 prefixes covering 2,048 addresses and 2 IPv6 prefixes.

About this network

TBG-NET-AS is operated by TBG OOD.

What it's used for

• The address space carries a mix of Cogent Communications, LLC and NETFINITY JSC allocations, alongside TBG OOD's own blocks identified by netnames BGLaptop and TBG-MRS1.
• The AS announces 2048 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, while maintaining 29 observed neighbours; this ratio of modest address space against a high neighbour count indicates a transit or interconnection role rather than a large access network.
• Traffic from this AS consists of business and enterprise connectivity, with the BGLaptop netname suggesting specific service segments for laptop or mobile broadband users within the Bulgarian market.

Notable

• Registrants for the largest prefixes are Cogent Communications, LLC and NETFINITY JSC, which differ from the AS holder TBG OOD, indicating leased or upstream transit space rather than direct ownership of those specific blocks.
• The address inventory is fragmented, combining /23 and /24 blocks from different original registrants, which is typical for a smaller operator aggregating transit and local allocations.
