About this network

The AS handle NETBOX-AS is held by Netbox Ltd.

What it's used for

• The address space carries residential and business internet access in Bulgaria, evidenced by netnames like BG-NETBOX-20160118 and NETBOXMododex, and reverse DNS entries pointing to ip.btc-net.bg.
• The AS announces 6,400 IPv4 addresses across 15 prefixes and maintains 20 observed neighbours, a ratio consistent with an access network providing last-mile connectivity rather than transit.
• Traffic from this AS consists of subscriber eyeballs and local business endpoints, as Netbox operates as a regional internet service provider in Bulgaria.

Notable

• Registrants largely align with the announcer, with most prefixes registered to NETBOX LTD or Neterra contacts, though two prefixes (77.78.40.0/23 and 77.78.52.0/23) are registered to Vivacom Bulgaria EAD under the netname BG-BTC-20070227.
• The address inventory is fragmented into multiple /23 and /24 blocks, reflecting a collection of smaller allocations rather than a single contiguous range.
