how to convert mac address to ipv4 address tool

To save the changes, run the command $ nmcli con up enps03 Next, change the addressing from DHCP to static. Then set up the DNS server: $ nmcli con mod enps03 ipv4.dns “8.8.8.8” Next, configure the default gateway as shown: $ nmcli con mod enps03 ipv4.gateway 192.168.2.1 We are going to configure a static IP with the following values: IP address: 192.168.2.20/24įirst, run the command below to set up the IP address. The current IP address is 192.168.2.104 with a CIDR of /24. In this example, we will modify the network interface enps03 to use a static IP.īut first, let’s check the IP address using IP command. This means that 2 24 (= 16.777.216) unique OUAs can be assigned per OUI.Using nmcli tool, you can modify a network interface to use a static IP address. Bit 25-48 (network adapter identifier): Bits 25 to 48 provide device manufacturers with 24 bits for assigning a unique hardware identifier (organizationally unique address, OUA).

A corresponding service is available, for example, on.

The assignment of OUIs is usually public and can be determined via databases.

Bit 3–24 (manufacturer identification): Bits 3 to 24 encode an identifier (organizationally unique identifier, OUI), which is assigned exclusively to hardware manufacturers by IEEE.

Addresses that are only locally unique are called locally administered address (LAA) and are marked with U/L = 1. If U/L = 0, the address is valid worldwide as a universally administered address (UAA).

Bit 2 (registry): The second bit of the MAC address indicates whether it is an address with global validity (universal) or whether the address has been assigned locally (local).

Multicast addresses are identified by I/G = 1 and are addressed to several receivers. If I/G = 0, it is a unicast address for a single network adapter. This bit is called I/G (short for individual/group).

Bit 1 (receiver): The first bit of the MAC address specifies whether it is an individual or group address.

The bit sequence of each MAC address is divided into 4 areas, each of which encodes different information.
