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 49-159-168-0.dynamic.elinx.com.tw and 49-158-196-0.dynamic.elinx.com.tw.
• The network announces 64,256 IPv4 addresses across 35 prefixes and 3 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, though one prefix (61.56.176.0/20) uses the netname ELANET-NET.
• The address inventory is finely subdivided into numerous /20, /21, and /22 blocks, consistent with a corporate estate managing site-by-site segmentation for its subscriber base.
