Le nom d'hôte est-il sensible à la casse ?

ayi

Is le hostname case sensitive? Is

ping MYHOST

equal to

ping myhost

Does it depend on le DNS used? Are there differences entre Win/Mac/Unix systems?

Names resolved depuis DNS are case insensitive. Ceci est important to prevent confusion. If it was case sensitive alors we would have eight variants of .com (.com, .Com, .cOm, .COm, .coM, .CoM, .cOM, et .COM). Country codes would have four.

If name resolution is case-sensitive for Ping it is pas being done by DNS.
