About this network

APT is the AS handle for FarEasTone Telecom, a major telecommunications provider in Taiwan.

What it's used for

• The address space carries mobile and residential customer traffic, evidenced by reverse DNS entries such as 218-184-64-0.cm.dynamic.apol.com.tw and netnames like FET.
• With 332,288 IPv4 addresses announced across 86 prefixes and 31 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants for the majority of the largest prefixes, including 218.184.0.0/16 and 210.85.128.0/17, are listed as IRT-FET-TW with the netname FET, aligning with the operator's identity.
• The address inventory is finely subdivided into numerous /18, /19, and /20 blocks, consistent with a large-scale consumer mobile and broadband estate.
• Some prefixes, such as 222.157.0.0/18, show different netnames like CCTV-HT-AP or ETWEBS-TW, suggesting historical allocations or specific service segments within the broader network.
