# Hostname Utilities
|
||
|
|
|
||
|
|
Functions for manipulating internet hostnames; in particular, for
|
||
|
|
converting between Unicode and ASCII-encoded forms of
|
||
|
|
Internationalized Domain Names (IDNs).
|
||
|
|
|
||
|
|
The
|
||
|
|
[Internationalized Domain Names for Applications (IDNA)](http://www.ietf.org/rfc/rfc3490.txt)
|
||
|
|
standards allow for the use
|
||
|
|
of Unicode domain names in applications, while providing
|
||
|
|
backward-compatibility with the old ASCII-only DNS, by defining an
|
||
|
|
ASCII-Compatible Encoding of any given Unicode name, which can be
|
||
|
|
used with non-IDN-aware applications and protocols. (For example,
|
||
|
|
“Παν語.org” maps to “xn--4wa8awb4637h.org”.)

## Hostname Conversions
|
||
|
|
|
||
|
|
* [func@GLib.hostname_to_ascii]
|
||
|
|
* [func@GLib.hostname_to_unicode]
|
||
|
|
|
||
|
|
## Hostname Checks
|
||
|
|
|
||
|
|
* [func@GLib.hostname_is_non_ascii]
|
||
|
|
* [func@GLib.hostname_is_ascii_encoded]
|
||
|
|
* [func@GLib.hostname_is_ip_address]
