Question How to interpret networking addresses in this format 192.168.1.0/24


Hi. I have been reading lots of articles on Redhat and noticed that sometimes the networking addresses are stated in the format of ip:netmask such as 192.168.1.3/255.255.255.0. I am familiar with this setup from networking articles. Some articles use this format --> 192.168.1.3/24 for example. How do I interpret the "24" in my example. Is it a netmask? If so, how do I translate its meaning?

Yes, the /24 is the netmask. It translates to 255.255.255.0 which you are more familiar with. Each octet in the netmask is 8 bits. A /30 network would translate to 255.255.255.252. This subnet calculator has a good converter at the bottom of the page.
