/**
 * A domain name service that resolves IP addresses for host names. Most applications will use the
 * [system DNS service][SYSTEM], which is the default. Some applications may provide their own
 * implementation to use a different DNS server, to prefer IPv6 addresses, to prefer IPv4 addresses,

http://192.168.0.257

# Invalid escaping should trigger the regular host error handling.

# Something that isn't exactly an IP should get treated as a host and
# spaces escaped.
http://192.168.0.1\shello

# Fullwidth and escaped UTF-8 fullwidth should still be treated as IP.

**Optional Fields**:
- `mimetype` - MIME type (default: text/html)
- `filetype` - File extension (default: html)
- `created` - Creation timestamp
- `timestamp` - Last modified timestamp
- `boost` - Document boost factor
- `label` - Access control labels

Es gibt jedoch bestimmte Fälle, in denen es nützlich ist, auf das `Request`-Objekt zuzugreifen.

## Das `Request`-Objekt direkt verwenden { #use-the-request-object-directly }

Angenommen, Sie möchten auf die IP-Adresse/den Host des Clients in Ihrer *Pfadoperation-Funktion* zugreifen.

Dazu müssen Sie direkt auf den Request zugreifen.
