Package io.netty.resolver.dns

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
DnsCache	A cache for DNS resolution entries.
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
DefaultDnsCache	Default implementation of DnsCache, backed by a ConcurrentMap.
DefaultDnsServerAddressStreamProvider	A DnsServerAddressStreamProvider which will use predefined default DNS servers to use for DNS resolution.
DnsAddressResolverGroup	A AddressResolverGroup of DnsNameResolvers.
DnsCacheEntry	Entry in DnsCache.
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.
MultiDnsServerAddressStreamProvider	A DnsServerAddressStreamProvider which iterates through a collection of DnsServerAddressStreamProvider until the first non-null result is found.
NoopDnsCache	A noop DNS cache that actually never caches anything.
NoopDnsQueryLifecycleObserverFactory
RoundRobinDnsAddressResolverGroup	A AddressResolverGroup of DnsNameResolvers that supports random selection of destination addresses if multiple are provided by the nameserver.
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.
