There is no specific meaning to any of the groups of numbers.

Both of those IP addresses are in the block of 172.111.139.0 to 172.111.139.255, which are assigned to a data center in NY.

Both of those IP addresses appear to be used as VPN servers, meaning the users of those IP addresses could be anywhere in the world.

Hello @1948mike,

An IP address is a unique identifier for a device on a network. It is usually represented in dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots. Each part represents a group of 8 bits (an octet) of the address. For example, the IP address 172.111.139.152 can be broken down into four octets: 172.111.139.131.

The slash and the number following it is just a shorthand way to write a subnet mask. It’s called CIDR (Classless Inter-Domain Routing) notation. It’s also commonly referred to as the prefix length. The number after the slash represents the number of consecutive 1’s in the subnet mask. The subnet mask is like masking when painting. You place a mask over what you DO NOT want to paint on.

To check if two IP addresses are on the same network, we need to know what network the first IP is on, and then see if the second IP is also on the same network. Knowing the subnet mask is the key when identifying if two IPs are on the same network or not.

In your case, the two IP addresses are 172.111.139.131 and 172.111.139.152. The subnet mask is /16, which means there are 16 consecutive 1’s in the binary representation of the address. Therefore, both IP addresses are on the same network with a prefix length of 16.

I hope this answers your questions
