Yes and no. Yes, if the IP address ending in. No if the IP address ending in. Add a comment. Active Oldest Votes. Improve this answer. Well, the broadcast address in your example still ends with. Matthias So? I didn't say the broadcast address doesn't end in , I just answered the question by giving an example of an IP address ending in that is not a broadcast address.

By the way, the opposite is also true: an address does not need to end in and still be a broadcast address. For example Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Sometimes "knowledgeable" users freak out a little thinking they've pulled an invalid IP, but from a networking POV it works fine.

Thanks for a good and clear answer. To slightly clarify, it depends upon how many bits are used for the hosts. When the network uses only 8 bits for the host address, the rule still applies. Alternatively, when more than 8 bits are used for the host address, the last byte CAN end in 0 or , because this not a violation of the rule. ThomasAdkins this didn't apply in my case. The Microsoft systems were making incorrect assumptions about my completely legal sub-netting.
