vrsn-end-of-zone-marker-dummy-record.root is a domain name listed in the DNS root zone as a diagnostic marker, whose presence demonstrates the root zone was not truncated upon loading by a root nameserver. It could be argued it represents a top-level domain of .root, although technically no such delegation exists.

According to the root zone file [http://www.internic.net/zones/root.zone] , the single .root entry was replaced in 2006 with just vrsn-end-of-zone-marker-dummy-record, to be reintroduced later in 2006 in its original form.

The existence of the record may be observed by querying for a TXT record for the domain name. On systems with the "dig" diagnostic tool installed, the query could be formulated as:

dig vrsn-end-of-zone-marker-dummy-record.root in any

or on Windows systems using the following command:

nslookup -type=any vrsn-end-of-zone-marker-dummy-record.root

This entry returns the word "", which is Latin for "full" or "complete". This may be a marker to signify the end of the zone file.

There is also a .root TLD in Open Root Server Network's rootzone named ORSN-END-OF-ZONE-MARKER-DUMMY-RECORD.ROOT. This entry returns the word "sic|europe".
