About this network

Autonomous System 4808 (CHINA169-BJ) is China Unicom's Beijing provincial network, part of the CHINA169 backbone that China Unicom inherited from China Netcom in northern China.

What it's used for

• Fixed broadband and business access for the Beijing municipality, carried on China Unicom's 169 backbone.

Notable

• One of the largest single ASNs on the internet by announced IPv4 space — millions of addresses, overwhelmingly serving end users. A textbook eyeball network.
• Chinese carriers split their networks by province, so this AS is specifically the Beijing region, not China Unicom as a whole. It is state-owned, and its international traffic is subject to national filtering.

Interesting

• The "169" in the name is a legacy of China Netcom's network branding; the two companies merged into China Unicom in 2008, but the CHINA169 naming persists throughout its routing registry entries.
