Class DnsLabel

  • All Implemented Interfaces:
    java.lang.CharSequence, java.lang.Comparable<DnsLabel>
    Direct Known Subclasses:
    LdhLabel, NonLdhLabel

    public abstract class DnsLabel
    extends java.lang.Object
    implements java.lang.CharSequence, java.lang.Comparable<DnsLabel>
    A DNS label is an individual component of a DNS name. Labels are usually shown separated by dots.

    This class implements Comparable which compares DNS labels according to the Canonical DNS Name Order as specified in RFC 4034 § 6.1.

    Note that as per RFC 2181 § 11 DNS labels may contain any byte.
