business taiwan ipv6

SGU-NET is the AS handle for See Get Upstart Technology Co., Ltd.

What it's used for

  • The space carries business traffic, evidenced by the netname TCSKY and registrant IRT-TCSKY-TW associated with the announced IPv4 prefix.
  • The AS announces 512 IPv4 addresses within a single /23 prefix and one IPv6 /32 prefix, while maintaining only 1 observed neighbour.
  • This low neighbour count relative to the address inventory indicates a direct peering or transit arrangement rather than a large-scale access or transit provider role.

Notable

  • The registrant IRT-TCSKY-TW and netname TCSKY align with the AS holder identity, confirming consistent ownership of the address space.
  • The address inventory consists of a single contiguous IPv4 block and a large IPv6 allocation, typical of a corporate or service provider estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
