Summary
Sustainable Development Networking Program (SDNP Bangladesh)
legacy isp hosting research
AS9825 (SDNP-BD-AS) belongs to the Sustainable Development Networking Program in Dhaka, Bangladesh. SDNP began as a UNDP initiative — part of a global programme to get developing-country institutions online — and after donor funding ended it was continued by the Sustainable Development Networking Foundation (SDNF), a registered not-for-profit that today runs ISP and data-centre services and operates BDIX, the Bangladesh Internet Exchange.
What it's used for
RIS sees 9 IPv4 prefixes carrying 2,304 addresses — nine individual /24s — with no IPv6 and 4 BGP neighbours. The blocks span both the organisation's original 202.59.208.0–202.59.211.0 allocation and newer APNIC 103.x and 163.61.x space, all from the same registry, which reads as a small operator that has picked up address space in /24 increments over a long life rather than as one growth event. Two thousand addresses and four upstreams is a small network by any measure: this AS carries the foundation's own hosting, colocation customers and connected institutions, not a subscriber base. Its significance in the Bangladeshi internet comes from the exchange it operates, not from the size of this address holding.
Notable
- The AS is small, but the organisation behind it is structurally important: BDIX is where much of Bangladesh's domestic traffic is exchanged, and keeping that traffic local is the whole point of the exchange.
- The UNDP origin explains the unusual name — SDNP nodes were set up in a number of developing countries under the same programme, so the handle is not unique to Bangladesh in spirit, only in this allocation.
- No IPv6 is announced.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
