SNI: The Unsung Hero of Secure Online Communication
Eliminates Multiple IP Addresses
In the early days of the internet, each website required a dedicated IP address, akin to a unique street address for a house. This posed a significant challenge as the number of websites proliferated, leading to a scarcity of IPv4 addresses, the prevalent IP address format at the time.
Server Name Indication (SNI) emerged as an ingenious solution to this dilemma. It allows multiple websites to coexist peacefully on a single IP address, much like multiple tenants residing in a single apartment building. SNI acts as a sophisticated mail carrier, seamlessly delivering users to the correct website based on the domain name they request.
This consolidation of websites onto shared IP addresses brought about a multitude of benefits. It alleviated the strain on the limited pool of IPv4 addresses, extending the lifespan of this vital resource. Moreover, it simplified server management, reduced costs for website owners, and enhanced overall network efficiency.
SNI's ability to eliminate the need for multiple IP addresses paved the way for a more scalable and sustainable internet infrastructure, accommodating the exponential growth of websites and online services we witness today.
