About this network

The AS handle UBBNET-AS-TW is held by Union Broadband Network.

What it's used for

• The address space carries residential broadband traffic, evidenced by reverse DNS entries such as 49-159-16-0.dynamic.elinx.com.tw and 180-218-144-0.dynamic.twmbroadband.net.
• The network announces 249088 IPv4 addresses across 107 prefixes and 9 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

• Registrants for the majority of prefixes are listed as IRT-UBBNET-TW with the netname UBBNET-NET, aligning with the AS holder, though some larger blocks like 203.77.0.0/19 show the netname TFN-NET.
• The address inventory is finely subdivided into numerous /20 and /21 blocks, consistent with a large-scale residential ISP managing customer-facing address space.
