What it's used for

This is a mid-sized national ISP's access network. The AS originates 31 IPv4 prefixes totalling 7,424 addresses, plus 2 IPv6 /48s (2404:9900:1::/48, 2404:9900:2::/48). The IPv4 inventory is almost entirely /24s with a couple of /22 aggregates (45.124.168.0/22, 103.4.144.0/22), spread across a broad set of APNIC ranges — 103.4, 103.136, 103.230, 103.245, 103.250, 43.224, 43.225, 45.124, 202.58. That accumulation of small, unrelated blocks is characteristic of a Bangladeshi ISP that has grown by taking whatever APNIC would allocate at each step; there is no single large legacy block underneath it. Only 4 BGP neighbours are observed, so the network buys transit from a handful of upstreams (Bangladesh's ISPs typically also sit on the BDIX exchange for domestic traffic) and is not itself a wholesale carrier. The address count is modest for a subscriber network, which fits an operator relying on carrier-grade NAT for its residential base.

Notable

• 31 prefixes for only 7,424 addresses: heavily fragmented space, the hallmark of incremental APNIC allocations rather than an early bulk assignment.
• IPv6 is present but minimal — two /48s, against 31 IPv4 routes.
• Next Online is a BDIX participant, so a meaningful share of its traffic is domestic peering that never appears as transit.
