What is an IP network mask? - Quora To add to the other answers with more bit-level detail: The reason it's called a "mask" is because the IP network mask is a number which is logical AND-ed with the IP address when treated as a number, to obtain the network address. Note that IPv4 AIX Network commands - UnixMantra Temporarily:# ifconfig en0 inet 192.168.100.9 netmask 255.255.255.0 up Permanently:# chdev -l en0 -a netaddr=192.168.100.10 -a netmask=0xffffff00

I'm trying to sniff traffic between my Leopard (10.5.7) host using Wireshark 1.0.2. Wireshark shows interfaces en0, en1, en3 and lo0, but ifconfig shows Sep 03, 2019 · auto enp0s3 iface enp0s3 inet static address 192.168.1.105 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 Configure IP address in Debian-based systems Save and close the file. Answer. Note: The term "vif" is depreciated in 8.0.x and above.It has been replaced by "ifgrp." You can add an alias to a vif or ifgrp using the following command: ifconfig vifname alias ip-address dm0: inet 192.168.1.140 netmask 0xffffff00 broadcast 192.168.1.255

This website explains how the network and broadcast addresses can be calculated via a netmask and a computer's ip address. To simplify that article: network is the lowest possible address in the range of ip addresses left over from the netmask. broadcast is the highest numbered ip address in that range.

5. Network Configuration - FreeBSD Instead of a generic ethX identifier that Linux ® uses to identify a network interface, FreeBSD uses the driver name followed by a number. The following output from ifconfig (8) shows two Intel ® Pro 1000 network interfaces (em0 and em1): % ifconfig em0: flags=8843 mtu 1500 options=b inet 10.10.10.100 netmask 0xffffff00 Netmask to IP Address Range Utility Tool | IPAddressGuide Netmask to IPv4 Conversion CIDR is the short for Classless Inter-Domain Routing, an IP addressing scheme that replaces the older system based on classes A, B, and C. A single IP address can be used to designate many unique IP addresses with CIDR. Static ip for freeNAS and jail system | iXsystems Community Apr 12, 2013 What is an IP network mask? - Quora
