Yuuta Network / AS142281 / AS4242422980


Yuuta Liang (ID: YuutaW)'s personal educational and research network.

The main purpose running YuutaNet is to learn some networking skills.

I run a few nodes and personal services on my network and I am open for peering.

Topology and Technologies

We have seven nodes across the world:


  • DN42: This node is available to DN42 network (AS4242422980)
  • UIX: This node is connected to Unmetered Exchange. Infers clearnet connectivity.
  • EVIX: This node is connected to EVIX. Infers clearnet connectivity.
  • OPTiX: This node is connected to OPTiX. Infers clearnet connectivity.
  • LLIX: This node is connected to LL-IX. Infers clearnet connectivity.
  • XXX Transit: This node connectes to XXX upstream ISP and serves as an ABR in YuutaNet. Infers clearnet connectivity.
  • Peering: This node is available for peering. See the Peering section below.
  • Core: This node is a part of the backbone network and is full-meshed.

United States:

  • San Jose 1: sjc1.us.nodes.yuuta.network, sjc1.us.yuuta.dn42 (DN42, EVIX, Peering, Core)
  • Seattle 1: sea1.us.nodes.yuuta.network (DN42, Vultr Transit, LSHIY Transit)


  • Toronto 1: yyz1.ca.yuuta.dn42 (DN42, Peeing, Core)
  • Vancouver 1: yvr1.ca.nodes.yuuta.network (DN42, UIX, EVIX, OPTiX, HE Transit, Peering)
  • My home: ca-1.yuuta.dn42 (DN42)

East Asia:


  • Tokyo 1: tyo1.jp.yuuta.dn42 (DN42, Peering, Core)

South Korea:

  • Seoul 1: icn1.kr.nodes.yuuta.network (Vultr Transit)



  • Frankfurt 1: fra1.de.yuuta.dn42 (DN42, Peering, Core)


  • Haarlem 1: har1.nl.nodes.yuuta.network (LLIX)

I deployed a /56 subnet to each geographical region. Currently, some random backbone nodes are full-meshed. Most nodes are intra-connected by iBGP and OSPF (all area 0).

I am planning to move away from full-meshing and give each geographical region an OSPF area. An upgrade to switch all clearnet regions from /56 to /48 for easier announcement is on the way.

Most nodes run Arch Linux at this time. We are considering to upgrade our architecture to NixOS for simpler management.

Particial topology diagram:

Administration and SSO: We currently deployed a LDAP server and a Kerberos KDC. They altogether provide unified identity and access management. Most of our nodes are enrolled in the LDAP and Krb system, which will enable NOCs to seamlessly logon to any servers.


YuutaW is the only NOC of YuutaNet. You may contact me at [email protected].

GPG Key: F99854A5DAA0D15DF2FEF89CBCD2B4B9E853C284.


We are open for peering!

For DN42 peering, you may use our auto peering system. It will setup our nodes immediatedly when you submit the peering form. Moreover, you may update your peering information or delete the connections at any time without contacting the NOC.

For clearnet peering, our most connections are established at IXs. For most IXs, we established the connection between our nodes with their route servers, which means you can just connect to their route server and you are ready to go. The whole list of peering locations could be found at our PeeringDB page. However, if you require some custom setup that require a dedicated BGP session, email our NOC. Keep in mind that this is a personal network so response time is not guaranteed.
