.ch is the Internet country code top-level domain (ccTLD) for Switzerland. It is administered by SWITCH Information Technology Services .
The use of "ch" may seem odd to someone who is not familiar with Switzerland. It does not come from the name for Switzerland in any of its national languages; "die Schweiz", "Suisse", or "Svizzera". Instead, it comes from Confoederatio Helvetica (Helvetic (Swiss) Confederation), the Latin name for the country (all Swiss coins are also stamped with this name).
