网络中的“10.0.0.1/32”是什么？

Question

What is the difference between 10.0.0.1/32 and 0.0.0.0/0 in.networking?

I am trying to fix this security issue by allowing all traffic through port 22 with cidr_block set to ( 0.0.0.0/0) . After research, 10.0.0.1/32 appears to fix this. However, what is the difference in this context?

Here is the issue https://docs.bridgecrew.io/docs.networking_1-port-security .

Answer 1

That is a CIDR block , which denotes a range of IP addresses. The CIDR block 0.0.0.0/0 denotes every IP address that exists, while the CIDR block 10.0.0.1/32 denotes the range 10.0.0.1 to 10.0.0.1 (in other words, the single IP address 10.0.0.1 ).

You can calculate the CIDR range using a utility like this one .
