L{ResolverBase} is a base class for implementations of
L{interfaces.IResolver} which deals with a lot
of the boilerplate of implementing all of the lookup methods.
@cvar _errormap: A C{dict} mapping DNS protocol failure response codes
to exception classes which will be used to represent those failures.

Resolve a name to an IP address, following I{CNAME} records and I{NS}
referrals recursively.
This is an implementation detail of L{ResolverBase.getHostByName}.
@param resolver: The resolver to use for the next query (unless handling
an I{NS} referral).
@type resolver: L{IResolver}
@param name: The name being looked up.
@type name: L{dns.Name}
@param answers: All of the records returned by the previous query (answers,
authority, and additional concatenated).
@type answers: L{list} of L{dns.RRHeader}
@param level: Remaining recursion budget. This is decremented at each
recursion. The query returns L{None} when it reaches 0.
@type level: L{int}
@returns: The first IPv4 or IPv6 address (as a dotted quad or colon
quibbles), or L{None} when no result is found.
@rtype: native L{str} or L{None}
