Description copied from class: DNSResolver

Lookup the IP addresses of a given host name. Returns null if there was an error, in which the error reason will be added in form of a HostAddress to failedAddresses. Returns a empty list in case the DNS name exists but has no associated A or AAAA resource records. Otherwise, if the resolution was successful and there is at least one A or AAAA resource record, then a non-empty list will be returned.

Concrete DNS resolver implementations are free to overwrite this, but have to stick to the interface contract.

Overrides:

lookupHostAddress0 in class DNSResolver

Parameters:

name - the DNS name to lookup

lookupFailures - list of exceptions that occurred during lookup.

dnssecMode - the selected DNSSEC mode

Returns:

A list, either empty or non-empty, or null

public static void setup()
