Fix issue #3163: corrected the IP-domain rlation statement

[EnTechGR]

CON-3163 | Corrected IP-Domain mapping documentation

Why?

The existing documentation contained a logical inaccuracy regarding the relationship between domain names and IP addresses. It stated that an IP address can only identify one domain name, which ignores the industry-standard practice of Virtual Hosting. This change ensures the technical documentation correctly reflects how modern web servers and DNS function.

Solution Overview

I have updated the descriptive text to clarify that the relationship between domain names and IP addresses is many-to-many.

The corrected statement now explains that:

1. One Domain can resolve to Multiple IPs (for load balancing).

2. One IP can host Multiple Domains (via Virtual Hosting/SNI).

Implementation Details

The revision replaces the restrictive "one-to-one" implication with a more accurate "many-to-many" explanation.

• Approach Chosen: Directly addressing the "Virtual Hosting" concept. This was chosen over a simple deletion because explaining why the numbers match the names provides better educational value for the project.

• Alternatives Considered: I considered adding a deep dive into SNI (Server Name Indication), but decided against it to keep the "Just Numbers" section concise and focused on the core concept of identifiers.

The "industry-standard of virtual hosting" has nothing to do with the fact that an IP can point only to one domain. For more info, read the reply at #3163 and its references.
