+* `dnssrv+` - the domain name after this prefix will be looked up as a SRV query, and then each SRV record will be looked up as an A/AAAA query. You do not need to specify a port as the one from the query results will be used. An example:

 ```

 ```
 
+* `dnssrvnoa+` - the domain name after this prefix will be looked up as a SRV query, with no A/AAAA lookup made after that. Similar to the `dnssrv+` case, you do not need to specify a port. An example:

 The default interval between DNS lookups is 30s. You can change it using the `store.sd-dns-interval` flag for `StoreAPI`
 configuration in `Thanos Query`, or `query.sd-dns-interval` for `QueryAPI` configuration in `Thanos Rule`.
