A relative name is always less than an absolute name. If both names have the same relativity, then the DNSSEC order relation is used to order them. *nlabels* is the number of significant labels that the two names have in common. Here are some examples. Names ending in "." are absolute names, those not ending in "." are relative names. ============= ============= =========== ===== ======= self other relation order nlabels ============= ============= =========== ===== ======= www.example. www.example. equal 0 3 www.example. example. subdomain > 0 2 example. www.example. superdomain < 0 2 example1.com. example2.com. common anc. < 0 2 example1 example2. none < 0 0 example1. example2 none > 0 0 ============= ============= =========== ===== ======= r r r[ ) r} � NAMERELN_NONErG r] r# �NAMERELN_COMMONANCESTOR�NAMERELN_SUPERDOMAIN�NAMERELN_SUBDOMAIN�NAMERELN_EQUAL) r �other�sabs�oabs�l1�l2�ldiffr^ �order�nlabels�namereln�label1�label2r r r � fullcompares sP � zName.fullcomparec C �( | � |�\}}}|tks|tkrdS dS )z�Is self a subdomain of other?

If ``None`` (the default), a ``bytes`` containing the wire name will be returned. *compress*, a ``dict``, is the compression table to use. If ``None`` (the default), names will not be compressed. Note that the compression code assumes that compression offset 0 is the start of *file*, and thus compression will not be correct if this is not the case. *origin* is a ``dns.name.Name`` or ``None``. If the name is relative and origin is not ``None``, then *origin* will be appended to it. *canonicalize*, a ``bool``, indicates whether the name should be canonicalized; that is, converted to a format suitable for digesting in hashes.
