K-20 Educational Network
DNS Cashing Servers
DNS cache servers run at all K-20 node sites. We recommend that district
staff install one or more DNS cache servers for their local machines and
point these cache servers to the K-20 DNS cache servers.
Two DNS Resolvers for all K-20 Network Cache Servers
We have installed a pair of DNS resolvers at each regional node site.
Each pair uses these IP addresses:
- ns1.wa-k20.net 22.214.171.124
- ns2.wa-k20.net 126.96.36.199
Important — these IP addresses are the same at every node.
It’s OK for district computers to point directly to the K-20 DNS cache servers but this set up doesn’t deliver the fastest or most efficient service to the user.
