In this video, explore how to change the ip address and subnet mask using both ifconfig and ip. Also, see how to create network interface aliases and delete them.

I needed to change a clients DHCP scope because I was changing their subnet from /24 to /16. I could have simply deleted and recreated the scope, but they has a lot of custom settings for their phone system, and hundreds of reservations (which I know is unusual). Solution. I wrote an article a long time ago about migrating DHCP scopes, this Jul 01, 2020 · It is called a subnet mask because it is used to identify network address of an IP address by perfoming a bitwise AND operation on the netmask. A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address. Subnet Mask is made by setting network bits to all "1"s and setting host bits Aside from what others have said about the new subnet mask. 1. double check every switch, router, firewall (nat translations, routng rules, interface/port definitions), server, printer, or device that has a static IP address prior to making the change, identifying each device that will need to have their subnet changed. Hi Brett, thanks for the response. I have 155+ devices (90+ Light switches/outlets, 40 security/landscape devices and the rest are wired connections for xbox, computers). During the holidays devices that require an ip address goes up. As you can imagine I am juggling to keep it within range. Not sure why the ability to change the subnet mask is - it matters the order in which you change the mask. Be sure to change the mask on the router interface before you change the mask on any of the end stations. - if you are running a dynamic routing protocol be sure that it will accept, process, and advertise the /23 mask. - when you change the mask on the router it will introduce some mismatch In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 - 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. There are three ways to confirm the address of subnet mask, gateway and DNS server: Login your router and choose the status of LAN, you can see the detailed information of subnet mask, gateway and DNS server. In fact, router’s LAN IP is just the gateway address. If you don’t know the DNS server, you can set it same with gateway.

So, again, a subnet mask of 255.255.255.0 indicates that the first three digits will all be the same on your network. Jul 03, 2019 · If you change the IP address for the default LAN subnet (LAN1), the LAN IP address for the router changes. In the IP Subnet Mask fields, enter the LAN subnet mask. If you change the IP subnet mask for the default LAN subnet, the LAN IP subnet mask for the router changes. Apr 17, 2012 · Change the subnet mask on the router and dc's first, then follow the instructions provided by Miles above. Next change the servers masks, then test the network with a laptop using on of the new addresses (static address for testing - don't turn on the new DHCP server until you have made sure that everything works).
