Or what is being sent to the authoritative servers.
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
dig +short TXT o-o.myaddr.l.google.com.
|
|
|
|
|
dig +short TXT whoami.ds.akahelp.net.
|
|
|
|
|
dig +short TXT whoami.ipv6.akahelp.net.
|
|
|
|
|
dig +short TXT whoami.ipv4.akahelp.net.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- Note: Cloudflare sends ECS only for whoami.ds.akahelp.net.
