AdGuard Home automatically gets the names of connected devices using reverse DNS
lookup (rDNS). It sends `PTR` requests with the IP addresses of clients to DNS
servers and uses the responses for “clients' human-friendly names”.
Using the domain-specific upstream notation, you can specify dedicated upstream
DNS servers for reverse DNS (rDNS) requests. If you want **all** your `PTR`
queries to be redirected to `192.168.8.8`:
Since **v0.106.0** you can enable and disable this feature with “Enable clients'
hostname resolution” setting in the “Upstream DNS servers” section or via the
`resolve_clients` field in the configuration file.
1. Enter the following into the “Upstream DNS servers” field on the “Settings
→ DNS settings” page:
Also since **v0.106.0** all the addresses from [private IP ranges][private-ip]
are only resolved via appropriate local resolvers to avoid the leaks of clients'
information. But you can also set custom upstreams for it in the “Private DNS
servers” field in the “Upstream DNS servers” section or via the
`local_ptr_upstreams` field in the configuration file. Note that the specified
upstreams are also used by DNS server to resolve `PTR` for the same IP range.
```none
[/in-addr.arpa/]192.168.8.8
[/ip6.arpa/]192.168.8.8
```
2. Enter the following into the “Private reverse DNS servers” field on the
same page below the previous field:
```none
192.168.8.8
```
There is no need to use the domain-specific notation here, unless you want
to redirect requests for different private ranges to different upstream
servers.
**NOTE:** All upstreams for private ranges **must** go to the “Private reverse
DNS servers” field **and not** the main “Upstream DNS servers” field. Entering
something like `[/192.in-addr.arpa/]192.168.8.8` into the main field will have
no effect.
Read below for more details.
#### <a href="#rdns-private" id="rdns-private" name="rdns-private">Private Addresses</a>
Since **v0.106.0** all the addresses from [private IP ranges][private-ip]
are only resolved via appropriate local resolvers to avoid leaks of clients'
information. By default, AdGuard Home tries to get the addresses of the default
resolvers from the OS. You can set custom upstreams for it in the “Private
reverse DNS servers” field in the “Upstream DNS servers” section or via the
`local_ptr_upstreams` field in the configuration file.
Since **v0.107.0** you can disable the usage of private reverse DNS upstream
servers via the “Use private reverse DNS resolvers” checkbox in the “Upstream
DNS servers” section or via the `use_private_ptr_resolvers` field in the
configuration file. If it is disabled, the unknown addresses from
locally served networks won't be resolved at all.
configuration file. If it is disabled, the unknown addresses from locally
served networks won't be resolved at all, and clients performing these queries
will receive `NXDOMAIN` responses.
But what if you want AdGuard Home to use another DNS server for a specific IP
address range? You can do it using the same syntax as for general upstream
servers, for example:
#### <a href="#rdns-public" id="rdns-public" name="rdns-public">Public Addresses</a>
If you want AdGuard Home to use another DNS server for a specific IP address
range, you can do it using the same syntax as for general upstream servers. For
example, if you add this to your “Upstream DNS servers” field:
```none
[/128.in-addr.arpa/]192.168.8.8
[/200.in-addr.arpa/]192.168.7.7
```
This rule instructs AdGuard Home to use `192.168.8.8` DNS server for all rDNS
requests to resolve clients' IP addresses from the `128.0.0.0/8` network.
then AdGuard Home will use the `192.168.7.7` DNS server for all rDNS requests to
resolve clients' IP addresses from the `200.0.0.0/8` network.
Note that if you want to use that address for `PTR` queries for IP addresses
outside of the locally served network ranges, you should also add this to your
main “Upstream DNS servers” field:
Note that if you want to use that address for `PTR` queries for IP addresses in
a locally served network range, for example `192.168.0.0/16`, you should add
this to the “Private reverse DNS servers” field:
```none
[/in-addr.arpa/]192.168.8.8
[/168.192.in-addr.arpa/]192.168.7.7
```
#### <a href="#rdns-clients" id="rdns-clients" name="rdns-clients">Client Look-Ups</a>
AdGuard Home automatically gets the names of connected devices using reverse DNS
lookup (rDNS). It sends `PTR` requests with the IP addresses of clients to
appropriate DNS servers and uses the responses to enrich client information with
human-friendly names.
Since **v0.106.0** you can enable and disable this feature with “Enable clients'
hostname resolution” setting in the “Upstream DNS servers” section or via the
`resolve_clients` field in the configuration file.
