Example 22 with InternetDomainName

use of com.google.common.net.InternetDomainName in project graylog2-server by Graylog2.

the class DnsClient method parseReverseLookupDomain.

 * Extract the domain name (without subdomain). The Guava {@link InternetDomainName} implementation
 * provides a method to correctly handle this (and handles special cases for TLDs with multiple
 * names. eg. for lb01.store.amazon.co.uk, only amazon.co.uk would be extracted).
 * It uses https://publicsuffix.org behind the scenes.
 * <p>
 * Some domains (eg. completely randomly defined PTR domains) are not considered to have a public
 * suffix according to Guava. For those, the only option is to manually extract the domain with
 * string operations. This should be a rare case.
