Unclassified APNIC
Summary
Union Broadband Network
residential broadband taiwan access
UBBNET-AS-TW is the AS handle for Union Broadband Network, a Taiwanese broadband operator.
What it's used for
- The address space carries residential dynamic IP addresses, evidenced by reverse DNS entries such as
49-159-116-0.dynamic.elinx.com.twand49-158-106-0.dynamic.elinx.com.tw. - The network announces 64,256 IPv4 addresses across 36 prefixes and 3 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
Notable
- Registrants for the largest prefixes are consistently
IRT-UBBNET-TWor unknown, with netnames uniformly set toUBBNET-NET, aligning with the AS holder identity. - The address inventory is finely subdivided into numerous /21 and /22 blocks, reflecting a segmented internal estate for a consumer broadband service.

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: 436 networks and 1,771 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.
