Let’s consider an oversimplified scenario.
The estimated number of domain name registrations across all top-level domains is approximately 367.3 million.
Assuming there are 5,939 domains associated with the same IP address, the probability that any given domain is assigned to that particular IP address is correctly calculated as 5,939 divided by 370,000,000, which equals approximately 0.000016.
If there are three individuals known to each other, and each individual has one website within that set of domains, the probability that all three websites randomly end up on the same IP address is obtained by raising the individual domain probability to the power of 3.
The resulting probability of approximately 4.096e-15, or roughly 1 in 244,140,625,000,000, indicates that the likelihood of all three websites ending up on the same IP address purely by chance is extremely low. This probability can be compared to winning the lottery multiple times to illustrate its rarity.
