Port, weight, and +priority all range from 0-65535. Weight and priority are optional; they +default to zero if not provided. + +Sconsole.zoinks.example.com:1.2.3.4:rack102-con1:2001:69:7:300: + +b) makes axfr-get decompose SRV and PTR records and write them out in +native format, rather than opaque. Again, this is necessary because if the +DNAME fields in the records reference the same zone as fqdn, they can have +compression pointers that are bogus outside the context of that specific +packet, and which can't be correctly loaded into data.cdb by tinydns-data. + +--michael + +Laurent G.
