Summary

Gansu Province Radio and Television Network Co., Ltd.

unknown · AI-generated

broadcasting media china enterprise

AS63719 is operated by Gansu Province Radio and Television Network Co., Ltd.

What it's used for

  • The address space carries the corporate network of a provincial broadcasting and television company, as indicated by the netname GSRTNC and registrant IRT-GSRTNC-CN for both announced IPv4 blocks.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated corporate or internal network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate communications, media production infrastructure, and administrative endpoints for the Gansu provincial broadcasting entity.

Notable

  • Registrants for both IPv4 prefixes (45.255.152.0/22 and 103.232.144.0/22) are consistent with the announcer, both listing GSRTNC as the netname and IRT-GSRTNC-CN as the registrant.
  • The address inventory is compact, consisting of two /22 IPv4 blocks and a single /32 IPv6 prefix, typical of a specific corporate site or departmental allocation rather than a broad service provider footprint.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
