What it's used for

This is a working access ISP, and the reverse DNS says so plainly. Nearly every sampled address resolves under bol-online.com, in a mix of formulaic customer naming (IP-96-005.bol-online.com, 103.129.244-005.bol-online.com, 42.5.bol-online.com) and named infrastructure hosts (mx3.bol-online.com, mx5.bol-online.com, switch01ep.dhaka.net). Customer-address templating plus in-house mail and switch records is the signature of a provider that both connects subscribers and runs services for them.

The routing backs it up. RIS sees 95 IPv4 prefixes carrying 17,920 addresses, 9 IPv6 prefixes, and 30 observed neighbours. Ninety-five announcements for under 18,000 addresses means heavy deaggregation: the estate is built out of a 182.163.96.0/19, a 202.84.32.0/20 and a 122.144.8.0/21 sliced down to /22s, /23s and smaller, plus later 103.x allocations. Thirty neighbours is a healthy local peering count for a national ISP — enough to show real presence at Bangladeshi exchange infrastructure, but nowhere near the fan-out of a wholesale carrier.

Notable

• The dhaka.net PTR on a switch address is a second domain the operator uses for infrastructure naming.
• The estate spans both older 202.x/122.x APNIC space and newer 103.x allocations, the usual pattern for a long-running provider that kept growing after the early blocks ran out.
