| Record | Type | Example |
|
||
|
|
|:-----------:|:--------------------|:---------------------------------------|
|
||
|
|
| A Record | IPv4 Address | "$domain".com |
|
||
|
|
| AAAA Record | IPv4 Address | "$domain".com |
|
||
|
|
| CNAME | Alternative Address | "$domain".rs, "$subdomain.$domain".com |
|
||
|
|
| NS | Nameserver | ns1.fastname.com |
|
||
|
|
| MX | Email server | "$domain".com |
|
||
|
|
| TXT | Literally anything,including ownership of a domain | |
|
||
|
|

|

|
Query a host with the `host` command.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
host $domain.$tld
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
```bash
|
||
|
|
host $domain.$tld 9.9.9.9
|
||
|
|
```
|
||
|
|
|
||
|
|
> dmz.rs has address 77.105.27.232
|
||
|
|
> dmz.rs mail is handled by 10 kralizec.dmz.rs.
|
||
|
|
> dmz.rs mail is handled by 20 splint.rs.
|
||
|
|
|
||
|
|
This shows the MX record has a secondary handler, called splint.rs.
|
||
|
|
|
||
|
|
You can also add a specific nameserver:
|
||
|
|
|
||
|
|
Request a specific record type (`CNAME`, `TXT`, et c.):
|
||
|
|
|
||
|
|
```bash
|
||
|
|
torsocks host -T -t $RECORD_TYPE $domain
|
||
|
|
```
|
||
|
|
|
||
|
|
## Troubleshooting
|
||
|
|
|
||
|
|
The `host` command uses UDP.
|
||
|
|
You can change to TCP by using `host -T`.
