Overview

A zone in a hash. A name the zone doesn't mention raises NoSuchName, a name without records of the type asked for raises NotFound, and the sentinels :timeout, :servfail, and :nxdomain stand in for a resolver that misbehaves rather than one that answers nothing — a distinction SPF spends a lot of its rulebook on.

FakeResolver.new("example.com" => { txt: [ "v=spf1 -all" ], mx: :servfail })

PTR is keyed by the address the caller passes rather than by its reverse name: a zone written by hand reads better as "192.0.2.1".

#addresses(name) ⇒ Object

A missing family contributes nothing; a name that doesn't exist at all, or a nameserver failure, still raises. Resolver#addresses, exactly.
