 This local resolver will be responsible for queries to the domain names of peers registered in your network and forwarding queries to upstream nameservers you configure in the system.

 #### Nameserver
 Nameserver is an upstream DNS server for name resolution, if a query comes and is not a peer domain name, it will be resolved by one of the upstream servers. You can assign private and public IPs and custom ports. Remember that you might need a network route for private addresses to allow peers to connect to it.
 #### Match domains
-Match domains allow you to route queries of names, matching them to specific nameservers. This is useful when you have an internal DNS configuration that only internal servers can resolve.
-#### All domains option
-The all domains option defines a default nameserver configuration to resolve all domains that don't have a match domain setting. Because not all operating systems support match domain configuration, we recommend configuring at least one nameserver set with this option enabled per distribution group. You may also consider using the group All for distribution, so you don't have to define multiple sets of nameservers to resolve all domains.
+By default, when creating nameserver groups without match domains, implies that the nameservers will resolve all DNS queries. For some cases, you might want to deploy a split horizon configuration for private or specific domains,  Match domains allow you to route queries of names, matching them to specific nameservers. This is useful when you have an internal DNS configuration that only internal servers can resolve.
+<Note>
+    Only MacOS, Windows 10+, and Linux running `systemd-resolved` support nameservers with only match domains. For a better experience, we recommend setting at least a nameserver group without match domains to be applied to the `All` group.
+</Note>
+#### Mark match domains as search domains
+Marking a match domain as search domains configures the peers to use only hostnames to perform FQDN queries. e.g. `ping host-a` instead of `ping host-a.netbird.cloud`.
 <Note>
-    A nameserver set may only be configured with either All domains or match domains, you can't have both settings in a single configuration as they overlap.
+    Marking a match domains as search domains feature is available in NetBird [v0.24.0](https://github.com/netbirdio/netbird/releases) or later.

 #### Distribution groups
 Distribution defines that peers that belong to groups set in this field will receive the nameserver configuration.
