AS10214 PENTANET-AS-AP Pentanet Limited

PENTANET-AS-AP is Pentanet Limited, a Perth-based licensed carrier and ISP that

sells home internet across Western Australia over its own fixed-wireless network

plus resold nbn fixed-line services.

What it's used for

• Consumer and small-business broadband in the Perth metro area. Pentanet runs its own metro fixed-wireless network of transmission towers and falls back to nbn where its wireless does not reach.
• RIS sees 48 IPv4 prefixes totalling 10,496 addresses and 7 IPv6 prefixes (2400:ec40::/32 and sub-allocations). The v4 blocks are the usual APNIC patchwork an Australian ISP accretes over time: 121.200.32.0/20, 103.46.212.0/22, 163.47.56.0/22, 160.20.72.0/22, 103.89.80.0/22.

Notable

• Eyeball access network, and the reverse DNS proves it rather than merely suggesting it. Sampled PTRs resolve to …static.wa.pentanet.network, …customer.as10214.net and, decisively, …cgn.wa.pentanet.network on 103.225.228.0/22. Carrier-grade NAT pools exist for one reason: to fan a single public address out across many subscriber sessions. You do not deploy CGN for servers, and wa names the state the customers live in.
• The 8 observed BGP neighbours confirm the role from the other side. A wholesale carrier peers with hundreds to thousands of ASes; a regional retail ISP buys transit from a few upstreams and sits at a local exchange. Ten thousand addresses fronted by CGN serves far more households than the raw count implies.

Interesting

• A backbone hop leaks into the sample as ve-1442-cgn01-p1.as10214.net — the operator names its own core interfaces after its AS number.
