AS24164 UBBNET-AS-TW UNION BROADBAND NETWORK
Unclassified APNIC
Summary
Union Broadband Network
residential broadband taiwan access
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.twand180-218-144-0.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-TWwith the netnameUBBNET-NET, aligning with the AS holder, though some larger blocks like203.77.0.0/19show the netnameTFN-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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 440 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
