The subnet mask is mostly used to work out whether another IP address can be accessed on the local network, or if it needs to go through a router. Your workstations with the old /24 subnet mask will have been able to access everything else that was inside the old /24 network, because the wrong mask will still give the right answer for those

The router knows the subnet mask(255.255.255.128) of the network. First, convert both the address into its binary equivalent. The network to which this IP address belongs can be easily be found by bitwise ANDing the subnet mask and the incoming IP address. TCP/IP (Internet Protocol) is a suite of communication protocols used to interconnect network devices (router, 10gbe switch and etc) on the internet. And an IP address, subnet mask and a default gateway are necessities in the TCP/IP configuration. 6. You still are using the default mask for your IP network 192.168.1.0. You need to subnet your network so that you have 5 additional networks, and 60 hosts per network. Is this possible, and what subnet mask should you use? No, it is not possible. 7. You have sub-netted your class C network 192.168.1.0 with a subnet mask of 255.255.255.240. Your Subnet Mask is going to appear as one of the parameters in the output under ¨Ethernet Adapters – Local Area Connection.¨ Another easy way you can see what your Subnet is by opening the Control Panel > Network & Internet > Network and Sharing Center > Local Area Connection and click on the Details button. Jun 15, 2020 · Changing the Subnet Mask of an interface So, I've had a brain fart. Is there a way to change the subnet mask of an IP address on a router or switch, without doing a 'no ip address?

Now lets look at why we subnet with different size masks. On the router we have got with 150.150.0.1 on fastethernet 0/0 and 150.150.1.1 on fastethernet 0/1 lets assume that we have a serial interface. What shall we do with addressing on the serial interface? If we use the same mask we can put address 150.150.2.1 on the serial.

I changed the subnet mask to .128 on all the computer and the DHCP server, as well as the router. Now, any client that has an IP address below .62 works fine, but any with an IP of .63 or higher has local connectivity but cannot reach the Internet. If your DHCP subnet mask on the Actiontec is not /25, then this is seriously messed up. spacedebris wrote: the IP addresses 192.168.1.100-150 are in a special range on the Verizon router reserved for STB's. Feb 14, 2019 · A single subnet mask limits the number of valid IPs for a specific network. Multiple subnet masks can organize a single network into smaller networks (called subnetworks or subnets). Systems within the same subnet can communicate directly with each other, while systems on different subnets must communicate through a router .

subnet mask (subnetting): A subnet mask is a 32- or 128- bit number that segments an existing IP address in a TCP/IP network and divides that address into discrete network and host addresses. The process of subnetting can further divide the host portion of an IP address into additional subnets to route traffic within the larger subnet .

I have my own router, which is why I am trying to change the subnet. I want to just use the homehub to pass the connection through to my own router and carry own using the normal subnet on there. (I meant change the subnet, not the subnet mask) The hub gives the option of 172.16.xx but won't actually let you select it Open a command prompt and run type: ipconfig /all. The list will show your settings for each adapter, including the DNS settings. Resulting like the following example: Subnet Mask – Type the subnet mask for the destination LAN IP address. Gateway – Type the IP address of the gateway server that enables communication between the router and the remote network. Interface – Select the location of the Destination LAN IP address. Click Show Routing Tables to view available static routes. Router Information 12. Question Which octet of the subnet mask 255.255.255.0 will tell the router the corresponding host ID? O The last octet The middle two octets O The first and last octet The first octet 13. Oct 17, 2019 · The CIDR number comes from the number of ones in the subnet mask when converted to binary. The common subnet mask 255.255.255.0 is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 ones, or /24 (pronounced ‘slash twenty four’). A subnet mask of 255.255.255.192 is 11111111.11111111.11111111.11000000 in binary, or 26 ones Because device 2's IP/Subnet mask put it on a different network then it's default gateway, so the traffic isn't ever reaching the router. 192.168.2.0/23 is 192.168.2.0-192.168.3.255.
