This construction consists of the equal of a zone click here name, the identified name servers for that zone, the identified addresses for that name servers, and background details which can be utilized to suggest which server is probably going being the ideal 1 to test up coming. The zone name equal is really a match rely of the amount of labels from the root down which SNAME has in prevalent Using the zone remaining queried; This is often employed to be a measure of how "shut" the resolver is to SNAME.
The concern section has a less complicated format when compared to the useful resource document structure used in the opposite sections. Each and every question document (there is often only one from the section) incorporates the following fields: Resource history (RR) fields
