What is Netmasking?
Netmasks (or subnet masks) are a shorthand for referring to ranges of consecutive IP addresses in the Internet Protocol. They used for defining networking rules in e.g. routers and firewalls. Every entity (server or client) communicating on the internet will have a unique Internet Protocol (IP) address.

What is subnet mask in Linux?
The subnet mask of an IP address is what tells the computer or router or whatever which part of your IP address belongs to your network and which part belongs to the hosts.
What is IP address and subnet mask?
IP addresses are either configured by a DHCP server or manually configured (static IP addresses). The subnet mask splits the IP address into the host and network addresses, thereby defining which part of the IP address belongs to the device and which part belongs to the network.
What is subnet mask in IP address?
A subnet mask is a 32- or 128-bit number that segments an existing IP address in a TCP/IP network. It is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. Once given the IP address and its subnet mask, the network address (subnet) of a host can be determined.
Is netmask same as subnet?
Netmask and subnet mask are often used as if they’re the same thing, but subnet masks are mostly used in network configurations, while netmasks often refer to classes of IP addresses. They’re used to define a range of IP addresses that an ISP or other organization can use.
What is a 255.255 255.0 subnet?
A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.
How to find the subnet mask of a Linux server?
Launch PuTTY and connect to Linux server. Run ifconfig command. You will see output of this command like below screenshot. Focus on the area which is highlighted in red colour. The IP address of this Linux server is 192.168.0.1 which is labeled as inet. You can see the subnet mask of this server which is showing 255.255.255.0 as netmask.

How do I communicate with a subnet in Linux?
Communication to and from a subnet is mediated by one specific port of one specific router, at least momentarily. Under UNIX / Linux, you need to use the ifconfig utility to assign an address to a network interface. and/or configure network interface parameters. Same command can display subnet.
How to check if mask is configured on an interface?
You can use the show running-config interfacecommand to check the mask configured on an interface. For eg. to check the mask configured on the loopback interface: R1#show running-config int lo1 interface Loopback1 ip address 10.1.1.1 255.0.0.0 end Expand Post LikeLikedUnlikeReply user365bam
