AS10081 DIGI-MY DiGi Telecommunications Sdn Bhd

DIGI-MY belongs to DiGi Telecommunications Sdn Bhd, one of Malaysia's three big mobile operators. DiGi merged with Celcom in 2022 to form CelcomDigi, but the AS and its handle still carry the older name.

What it's used for

The space in this AS is mobile subscriber territory — the address pools behind DiGi's mobile data network, handed out to handsets and mobile broadband devices as they attach. That is the whole point of a block this shape: a cellular core does not need many prefixes, it needs a few large contiguous ones it can hand out from.

Notable

This is mobile, and the prefix geometry is the argument. RIS sees only 2 IPv4 prefixes but 40,960 addresses: a 116.197.0.0/17 and a 203.92.128.0/19. That ratio is the tell. Forty thousand addresses in two aggregates means the operator has never had a reason to deaggregate — there are no customer sites to steer independently, because there are no customer sites, only subscribers attaching to a GGSN or PGW that owns the whole pool. Contrast an enterprise or regional ISP of the same address count, which would show dozens of /24s. The single observed neighbour fits: this AS sits behind DiGi's own upstream rather than peering on its own account, which is common when a group runs a separate AS for the mobile data plane.

Interesting

Expect these addresses to geolocate poorly at city level. Mobile pools are anchored to gateway sites, not to where the phone actually is, and a Malaysian subscriber in Sabah may present from a pool that reads as Kuala Lumpur.
