DNS Resolver Status¶
The DNS Resolver status page at Status > DNS Resolver displays the current contents of the DNS resolver infrastructure cache.
The page contains a variety of statistics for DNS servers contacted by the resolver daemon (Unbound), though the type of content varies based on the current DNS resolver mode.
In resolver mode the status page contains a list of all authoritative DNS servers which Unbound has recently contacted along with the zone for which they were queried.
The page will typically contain entries for root servers (
. zone), Top Level
Domain (TLD) servers (e.g.
.org) and servers for specific domains.
When there are multiple servers for the same zone, the statistics tracked in the
cache help Unbound decide which server it will use for subsequent queries.
In forwarding mode the status page contains entries for each of the available forwarding DNS servers. These DNS Servers are from the list configured on System > General Setup as well as from dynamic WAN sources, when present.
The statistics tracked in the cache help Unbound decide which server it will use for subsequent queries. For example, in a multi-WAN environment a server routed through a failed WAN would be marked as unresponsive and skipped. A server connected to a slow or high latency WAN would be skipped unless better sources were unavailable.
