- io.netty5.resolver.dns.DefaultDnsServerAddressStreamProvider

All Implemented Interfaces:

DnsServerAddressStreamProvider
```
public final class DefaultDnsServerAddressStreamProvider
extends Object
implements DnsServerAddressStreamProvider
```
A DnsServerAddressStreamProvider which will use predefined default DNS servers to use for DNS resolution. These defaults do not respect your host's machines defaults.
This may use the JDK's blocking DNS resolution to bootstrap the default DNS server addresses.

    Description copied from interface: DnsServerAddressStreamProvider
    
    Ask this provider for the name servers to query for hostname.
    
    Specified by:
    
    nameServerAddressStream in interface DnsServerAddressStreamProvider
    
    Parameters:
    
    hostname - The hostname for which to lookup the DNS server addressed to use. If this is the final DnsServerAddressStreamProvider to be queried then generally empty string or '.' correspond to the default DnsServerAddressStream.
    
    Returns:
    
    The DnsServerAddressStream which should be used to resolve hostname.
  - defaultAddressList
```
public static List<InetSocketAddress> defaultAddressList()
```
    Returns the list of the system DNS server addresses. If it failed to retrieve the list of the system DNS server addresses from the environment, it will return "8.8.8.8" and "8.8.4.4", the addresses of the Google public DNS servers.
  - defaultAddresses
```
public static DnsServerAddresses defaultAddresses()
```
    Returns the DnsServerAddresses that yields the system DNS server addresses sequentially. If it failed to retrieve the list of the system DNS server addresses from the environment, it will use "8.8.8.8" and "8.8.4.4", the addresses of the Google public DNS servers.
    This method has the same effect with the following code:
    DnsServerAddresses.sequential(DnsServerAddresses.defaultAddressList());
