Description
IP addresses serve for a general host identification purposes in IP networks. Typical (IPv4) address consists of four octets. For proper addressing the router also needs the network mask value, id est which bits of the complete IP address refer to the address of the host, and which – to the address of the network. The network address value is calculated by binary AND operation from network mask and IP address values. It’s also possible to specify IP address followed by slash “/” and amount of bits assigned to a network mask.
In most cases, it is enough to specify the address, the netmask, and the interface arguments. The network prefix and the broadcast address are calculated automatically. It is possible to add multiple IP addresses to an interface or to leave the interface without any addresses assigned to it. Leaving a physical interface without an IP address is not a must when the bridging between interfaces is used. In case of bridging, the IP address can be assigned to any interface in the bridge, but actually the address will belong to the bridge interface. You can use /ip address print detail to see to which interface the address belongs to. MikroTik RouterOS has following types of addresses:
• Static – manually assigned to the interface by a user
• Dynamic – automatically assigned to the interface by estabilished ppp, ppptp, or pppoe connections
Example
[admin@MikroTik] ip address> add address=10.10.10.1/24 interface=ether2
[admin@MikroTik] ip address> print
Flags: X – disabled, I – invalid, D – dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 2.2.2.1/24 2.2.2.0 2.2.2.255 ether2
1 10.5.7.244/24 10.5.7.0 10.5.7.255 ether1
2 10.10.10.1/24 10.10.10.0 10.10.10.255 ether2
[admin@MikroTik] ip address>
