What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS entries such as
119-15-232-0.veetime.comandh254.c219.GTBC.com.tw, and netnames likeEMAX-NETandGTBC-NET. - The AS announces 154,368 IPv4 addresses across 51 prefixes and 17 IPv6 prefixes, while maintaining 43 observed neighbours; this ratio of substantial address inventory to a moderate peer count indicates an access or eyeball network role.
Notable
- Registrants vary across the inventory, including
DONGFONG-TW,IRT-VEETIME-1-TW,IRT-GTBC-TW,IRT-TAIFO7716-TW, andIRT-CHIEF-TW-TW, suggesting the AS aggregates space from multiple entities or historical acquisitions. - The inventory includes a mix of large blocks like
87.80.0.0/16and78.105.0.0/18alongside numerous smaller /20 and /22 prefixes, reflecting a diverse and segmented address estate.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
