Summary
Melsa (PT Melvar Lintasnusa)
isp residential legacy
AS9657 (MELSANET-ID-AP) is held by PT Melvar Lintasnusa, trading as Melsa — an internet service provider based in Bandung, West Java. It is one of Indonesia's early ISPs, operating since the mid-1990s, and it sells access to homes, businesses and government offices in and around the city. Melsa is PeeringDB-listed and runs a public looking glass under melsa.net.id.
What it's used for
The routing shows a regional access provider that has kept up with modern practice. RIS sees 32 IPv4 prefixes totalling 8,192 addresses and, notably, 16 IPv6 prefixes from 2403:9500::/32, announced through 9 observed neighbours.
The IPv4 side is one legacy 202.138.x range broken into /24s — 202.138.225.0/24 through 202.138.254.0/24 — which is what an ISP of this vintage looks like when it has one old allocation and carves it up by service and POP. The IPv6 side is more interesting: sixteen /36s deaggregated out of a /32 is a lot of announcement granularity, and it suggests IPv6 is being handed out in earnest rather than sitting unused. Nine neighbours against 8,192 addresses is an eyeball-network shape, not a transit one — a wholesale carrier of this age would peer with hundreds.
Sampled reverse DNS returns mail.pt-panjunan.com, a customer's own domain rather than a Melsa-branded access pool, which is a reminder that PTRs show what the space carries, not who holds it.
Notable
- The IPv6 footprint is out of proportion to the IPv4 one, a healthy sign for an ISP whose v4 allocation is capped at a single legacy range.

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 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
