About this network

AS9246 (GTA-AP) is held by Teleguam Holdings, LLC, trading as GTA — the principal telecommunications company on Guam. GTA sells fibre and DSL broadband, mobile, voice and television to residents and businesses on the island, and also operates cable landing station and data centre facilities.

What it's used for

This is an island incumbent's eyeball network, and the reverse DNS is explicit about it. Sampled addresses resolve under teleguam.net with role-encoded names: 114-142-224-5.dsl.teleguam.net and 43-240-88-5.dsl.teleguam.net for consumer access, .biz.static.teleguam.net for business customers on static addresses, and .core.static.teleguam.net on infrastructure. A carrier that labels its own space dsl, biz and core is telling you exactly how it is segmented.

RIS sees 10 IPv4 prefixes carrying 34,816 addresses plus a 2405:7400::/32, against 27 observed neighbours. The address count is large relative to Guam's population, which is what an incumbent that has been assigning space for decades looks like. The 27 neighbours are more interesting: that is well above what a pure access network of this size would need, and reflects Guam's position as a Pacific cable hub — GTA lands and interconnects with networks moving traffic between Asia and North America, so it accumulates peering that an equivalently sized mainland ISP would not.

Notable

• The estate mixes APNIC space (114.142.192.0/18, 202.151.64.0/19, 103.7.100.0/22) with ARIN-region blocks (38.121.24.0/21, 67.98.160.0/21, 209.164.184.0/21), a natural consequence of Guam being a US territory inside the APNIC service region.
• GTA's infrastructure includes cable landing stations and data centre space serving carriers and hyperscalers transiting the Pacific.
