# dns_fetch.py
This lovely python script allows you to fetch ip address form cloudflare dns records. Useful for remote servers with dynamic ips. You can define the env file "dns_resolv_env.json" as follows:
```
{
        "auth_key": "key here (required without --auth)",
        "zone_id": "zone id here (optional)",
        "default_name": "website name here (optional)"
}
```
The script has many useful featues:
- `python3 dns_fetch.py -a -n -i` 
    - Returns only the ip address of the A record corresponding to default_name.
        - This can be used in bash commands: `ssh username@$(python3 dns_fetch.py -a -n -i)`
- `python3 dns_fetch.py -a` 
    - Returns all A records
- `python3 dns_fetch.py -c`
    - Returns all CNAME records
- `python3 dns_fetch.py`
    - Prints the raw json from cloudflare
- `python3 dns_fetch.py -n`
    - Prints all records corresponding to default_name
