Which browsers support SNI?

Question

Because of the way web servers and SSL work, previously a dedicated IP address was required for running an SSL certificate on a domain.

But with a new technique (SNI, abbreviation for Server Name Indication) this is no longer a requirement. So which browsers do and do not support SNI?
