io.netty5.resolver.dns (Netty API Reference (5.0.0.Alpha4))

An alternative to Java's built-in domain name lookup mechanism that resolves a domain name asynchronously, which supports the queries of an arbitrary DNS record type as well.

Interface Summary
Interface	Description
AuthoritativeDnsServerCache	Cache which stores the nameservers that should be used to resolve a specific hostname.
DnsCache	A cache for DNS resolution entries.
DnsCacheEntry	Represents the results from a previous DNS query which can be cached.
DnsCnameCache	A cache for `CNAME`s.
DnsQueryLifecycleObserver	This interface provides visibility into individual DNS queries.
DnsQueryLifecycleObserverFactory	Used to generate new instances of `DnsQueryLifecycleObserver`.
DnsServerAddressStream	An infinite stream of DNS server addresses.
DnsServerAddressStreamProvider	Provides an opportunity to override which `DnsServerAddressStream` is used to resolve a specific hostname.

Class Summary
Class	Description
BiDnsQueryLifecycleObserver	Combines two `DnsQueryLifecycleObserver` into a single `DnsQueryLifecycleObserver`.
BiDnsQueryLifecycleObserverFactory	Combines two `DnsQueryLifecycleObserverFactory` into a single `DnsQueryLifecycleObserverFactory`.
DefaultAuthoritativeDnsServerCache	Default implementation of `AuthoritativeDnsServerCache`, backed by a `ConcurrentMap`.
DefaultDnsCache	Default implementation of `DnsCache`, backed by a `ConcurrentMap`.
DefaultDnsCnameCache	Default implementation of a `DnsCnameCache`.
DefaultDnsServerAddressStreamProvider	A `DnsServerAddressStreamProvider` which will use predefined default DNS servers to use for DNS resolution.
DnsAddressResolverGroup	A `AddressResolverGroup` of `DnsNameResolver`s.
DnsNameResolver	A DNS-based `InetNameResolver`.
DnsNameResolverBuilder	A `DnsNameResolver` builder.
DnsServerAddresses	Provides an infinite sequence of DNS server addresses to `DnsNameResolver`.
DnsServerAddressStreamProviders	Utility methods related to `DnsServerAddressStreamProvider`.
LoggingDnsQueryLifeCycleObserverFactory	A `DnsQueryLifecycleObserverFactory` that enables detailed logging in the `DnsNameResolver`.
MultiDnsServerAddressStreamProvider	A `DnsServerAddressStreamProvider` which iterates through a collection of `DnsServerAddressStreamProvider` until the first non-`null` result is found.
NameServerComparator	Special `Comparator` implementation to sort the nameservers to use when follow redirects.
NoopAuthoritativeDnsServerCache	A noop `AuthoritativeDnsServerCache` that actually never caches anything.
NoopDnsCache	A noop DNS cache that actually never caches anything.
NoopDnsCnameCache
NoopDnsQueryLifecycleObserverFactory
RoundRobinDnsAddressResolverGroup	A `AddressResolverGroup` of `DnsNameResolver`s that supports random selection of destination addresses if multiple are provided by the nameserver.
SequentialDnsServerAddressStreamProvider	A `DnsServerAddressStreamProvider` which is backed by a sequential list of DNS servers.
SingletonDnsServerAddressStreamProvider	A `DnsServerAddressStreamProvider` which always uses a single DNS server for resolution.
UnixResolverDnsServerAddressStreamProvider	Able to parse files such as /etc/resolv.conf and /etc/resolver to respect the system default domain servers.

Exception Summary
Exception	Description
DnsNameResolverException	A `RuntimeException` raised when `DnsNameResolver` failed to perform a successful query.
DnsNameResolverTimeoutException	A `DnsNameResolverException` raised when `DnsNameResolver` failed to perform a successful query because of an timeout.
