### DNS { #dns }

Ahora centrémonos en todas las partes realmente de HTTPS.

Primero, el navegador consultaría con los **servidores DNS** cuál es la **IP del dominio**, en este caso, `someapp.example.com`.

## Version 5.0.0-alpha.3

_2021-11-22_

 *  Fix: Change `Headers.toString()` to redact authorization and cookie headers.
 *  Fix: Don't do DNS to get the hostname for `RecordedRequest.requestUrl`. This was doing a DNS
    lookup for the local hostname, but we really just wanted the `Host` header.
 *  Fix: Don't crash with a `InaccessibleObjectException` when detecting the platform trust manager

controlled by the [`execerrdot` setting](/pkg/os/exec#hdr-Executables_in_the_current_directory).
There is no plan to remove this setting.

Go 1.19 started sending EDNS0 additional headers on DNS requests.
This can reportedly break the DNS server provided on some routers,
such as CenturyLink Zyxel C3000Z.
This can be changed by the [`netedns0` setting](/pkg/net#hdr-Name_Resolution).

- Fixed a regression introduced in v1.29 where conntrack entries for UDP connections
  to deleted pods did not get cleaned up correctly, which could (among other things)
  cause DNS problems when DNS pods were restarted. ([#127780](https://github.com/kubernetes/kubernetes/pull/127780), [@danwinship](https://github.com/danwinship))

- Allowed setting the `hostnameOverride` field in `PodSpec` to specify any RFC 1123 DNS subdomain as the pod's hostname. The `HostnameOverride` feature gate was introduced to control enablement of this functionality. ([#132558](https://github.com/kubernetes/kubernetes/pull/132558), [@HirazawaUi](https://github.com/HirazawaUi)) [SIG API...

### Feature

- Added `k8s-short-name` and `k8s-long-name` format validation tags to enforce DNS label and DNS subdomain compliance. ([#133894](https://github.com/kubernetes/kubernetes/pull/133894), [@lalitc375](https://github.com/lalitc375))
