Network type: hosting

AS4842 announces 1 IPv4 prefixes covering 256 addresses and 8 IPv6 prefixes.

About this network

Autonomous System 4842 (TH-AS-AP) is operated by Tianhai InfoTech, a small Chinese network operator based in Changsha, Hunan, which runs its network under the name Tianhai Global Network.

What it's used for

• A small, globally peered network. It announces only a single IPv4 /24 but a large amount of IPv6, and it peers widely at internet exchanges under an open peering policy.

Notable

• The IPv4/IPv6 imbalance is the interesting part: essentially all of this network's reach is on IPv6, with IPv4 kept to a token block. That is a shape you see in operators who built out after IPv4 exhaustion.
• Despite the low AS number, this is a modern, small-scale operator rather than an early-internet network, so read nothing into the four-digit ASN.
