Features of SNI
- Cost savings: Obtaining and using IP addresses comes at a high cost. SNI contributes to the reduction of the requirement for extra IP addresses while hosting several websites. As a result, significant financial savings are possible because extra IP addresses are not required.
- Compatibility: Because SNI is supported by most modern web browsers and servers, it is a commonly used solution for hosting multiple secure websites on a single server.
- Multiple certificates: SNI allows the installation of multiple SSL/TLS certificates on a single server, allowing the hosting of many domain names on the same IP address.
- Enhanced Performance: SNI increases server capacity and optimizes resource usage, which can speed up webpages.
What is Server Name Indication (SNI)?
All that a server name is is the computer’s name. Unless the server hosts a single domain and the server name is the same as the domain name, this name is not displayed to end users for web servers. An addition to the Transport Layer Security computer networking protocol is called Server Name Indication, which enables the client to provide the hostname it is attempting to connect to at the outset of the handshaking procedure.
