About this network

AS9676 (SAVECOM-TW) is held by SaveCom International Inc. (宏遠電訊), a Taipei-based Taiwanese telecommunications company and consumer broadband ISP that trades on the domain savecom.net.tw. SaveCom runs more than one ASN; this one carries the bulk of its subscriber address space.

What it's used for

This is an eyeball access network. RIS sees 300 IPv4 prefixes carrying 251,904 addresses, plus 2 IPv6 prefixes (2402:9c00::/32 and 2407:680::/33), reaching the internet through only 4 observed BGP neighbours. Few neighbours against a quarter-million addresses is the access-network signature: the network exists to connect its own users, not to sell transit to other ASes. The IPv4 inventory is anchored on /17s and /18s in 61.65.0.0, 122.201.128.0, 118.99.128.0, 60.245.0.0 and 101.0.128.0 space, then broken down aggressively. 300 announcements over 246 /24-equivalents means the network is announcing most of its space in small pieces, typical of a provider that has accumulated non-contiguous allocations and pins them to different aggregation points.

The reverse DNS settles the role: sampled addresses across every major block resolve to per-address subscriber names under savecom.net.tw (5-64-65-61.savecom.net.tw and similar), the auto-generated PTR pattern of a residential broadband pool.

Notable

• Consumer traffic from this AS is Taiwanese retail broadband, so it behaves as an eyeball source rather than a hosting or datacentre origin.
• The heavy deaggregation is a routing-table cost worth knowing about: this single AS contributes 300 IPv4 entries for a fairly modest address holding.
