 Tier 2 servers are "DNS Resolvers" or, servers that actually do the heavy-lifting when querying OpenNIC's DNS infrastructure. These are the servers that **clients use in their configuration** directly, and they provide access to the network. Anybody can operate a Tier 2 server, but there is a large amount of "Public Tier 2" servers to choose from at [[http://servers.opennicproject.org/|servers.opennicproject.org]]. Tier 2 servers are "DNS Resolvers" or, servers that actually do the heavy-lifting when querying OpenNIC's DNS infrastructure.

 We don't recommend you run it from a home connection, unless you have a high bandwidth and **low latency connection** with no bandwidth caps. Low WAN latency is important for running a DNS server, because the server itself is in charge of lookups, and high latency (e.g. on a home connection) can slow down requests dramatically compared to a server hosted with a low-latency connection in a datacenter. This graphic is a vast oversimplification of the DNS process but demonstrates why hosting at home is rarely a good idea: We don't recommend you run it from a home connection, unless you have a high bandwidth and **low latency connection** with no bandwidth caps.

 The first graphic is an example of a Tier 2 server hosted at home. It needs to make numerous requests to "[[opennic:tier1|Authoritative]]" DNS servers, which are slowed down by the latency of the home connection. The second graphic has a higher latency between the user and the Tier 2 server, because it's outside the LAN, but the speed increases when communicating with Authoritative servers create a faster experience overall. The first graphic is an example of a Tier 2 server hosted at home.
