John Wagnon digs into the TSL server name indication extensionwhat it is, what it does, why it's useful, etc. Server Name Indication TLS does not provide a mechanism for a client to tell a server the name of the server it is contacting. It may be desirable for clients to provide this information to facilitate secure connections to servers that host multiple 'virtual' servers at a single underlying network address. 4) SNI(Server Name Indication) 차단 이번에 새롭게 빼어든 칼날입니다. TLS 프로토콜 확장 항목에 기재되는 목적지 호스트 정보를 이용해 유해사이트 접속을 차단하는 방식입니다. SNI(Server Name Indication)用来解决一个服务器拥有多个域名的情况之前的 SSL 握手信息中并没有携带客户端要访问的目标地址。这样会导致一个问题,如果一台服务器有多个虚拟主机,且每个主机的域名不一样,使用了不一样的证书,该返回哪一个给客户端? Server name indication isn’t all benefits. For example, SNI isn’t supported by all web browsers - although this admittedly only effects a small number of users.

For more explanation, see our post on TLS vs. SSL. Server Name Indication (SNI) allows the server to safely host multiple TLS Certificates for multiple sites, all under a single IP address. This is because the SSL/TLS handshake occurs before the client device indicates over HTTP which website it's connecting to. Server Name Indication (SNI) is designed to solve this problem. SNI is an extension for the TLS protocol (formerly known as the SSL protocol), which is used in HTTPS.
