Typically if an IP address ends in , that will be a broadcast IP. Improve this question. Yes and no. Yes, if the IP address ending in. No if the IP address ending in. Add a comment.

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.
If you are using If you have a sub net mask of If some of your PC's are not getting out to internet, then I can only guess that your router is blocking the new range. By doing so you'll double your available IP's. By doing this X and X will be on the same range. This gives you IP's. Is that what you want? Or do you want more? How many more devices do you need to connect?
Would essentially doubling the size of your network cover it or would you need more than that? Do you have other networks connecting to you via VPN or any chance of someone else being on the 1. As others have said, to go to a I'd suggest moving the front end of your dhcp scope to say 0. That way if you add a server later on, a new printer, etc.
Taking the question at face value: I don't think you understand IP addresses. You cannot go beyond for a single 'field' octet in an IP address. IPs are 32 bits long, nominally defined as four 8 bit octets. This can be written in hexadecimal as 00 to FF, or in decimal as 0 to A subnet mask is a way of defining how many of those bits are used to identify the network, and how many are used to identify the hosts in that network.
We used to write these as For example, this is That's 24 1's and 8 0's. Rather than always writing out Back to our example: To figure out how big your range can be with a single netmask you can write it out in binary. With a network address of For example have your existing There are really two types of IP assignments: dynamic and static.
A dynamic IP address is assigned automatically when a device connects to a network. DHCP is built into your router. When a device connects to the network, it sends out a broadcast message requesting an IP address. There are certain private IP address ranges routers will use for this purpose.
Which is used depends on who made your router, or how you have set things up yourself. Those private IP ranges include:. The thing about dynamic addresses is that they can sometimes change. DHCP servers lease IP addresses to devices, and when those leases are up, the devices must renew the lease. Sometimes, devices will get a different IP address from the pool of addresses the server can assign. Occasionally, however, you might want to give a device an IP address that does not change.
For example, maybe you have a device that you need to access manually, and you find it easier to remember an IP address than a name. Or maybe you have certain apps that can only connect to network devices using their IP address. In those cases, you can assign a static IP address to those devices. There are a couple of ways to do this. You can manually configure the device with a static IP address yourself, although this can sometimes be janky. The other, more elegant solution is to configure your router to assign static IP addresses to certain devices during what would normally be dynamic assignment by the DHCP server.
