If you do some Goggling on configuring static IP addresses etc then you will come across many tutorials that take you through either editing the /etc/networking/interface file or /etc/dhcp/nf file. I have also disabled ipv6 on these interfaces. I’ve also enable the checkbox Automatically configure empty options and because of this the default Gateway (router) and the DNS server addresses will come from the DHCP server. In the screen shot below I have configured the Wireless Interface to use a static IP address of 192.168.1.42 and the Ethernet Interface to have an IP address of 192.168.1.41 To make changes you first need to select the Interface using the drop down box. However for most of us using a GUI is easier and PI provide one in the top right task bar. ![]() They are:īeing Linux then there are several commands and configuration files that need to be used/edited. In order for a computer to be part of a DNS domain, it must be given a DNS suffix (here mydomain.There are a number of common requirements that require configuration. A DNS domain is not, of course, limited to a single physical network. The fully qualified machine name ( FQDN) becomes .Ī set of computers can be grouped into a logical, name-resolving, set called a DNS domain. IP and MAC addresses must be unique on a network! DNS Domain ¶Ĭlient machines can be part of a DNS ( Domain Name System, e.g. Also to avoid confusion in a URL, the IPv6 address is written in square brackets, colon, port address. In a web address or URL (Uniform Resource Locator), an ip address can be followed by a colon and the port address (which indicates the application to which the data is destined). Insignificant zeros can be omitted, one or more groups of 4 consecutive zeros can be replaced by a double colon. IPv6 is often represented by 8 groups of 2 bytes separated by a colon. The number of available addresses being close to saturation a new standard was created, the IPv6 defined on 16 bytes. The relative size of each part varies according to the network (sub)mask.Īn IPv4 address defines an address on 4 bytes. One part defines the network address (NetID or SubnetID as the case may be), the other part defines the address of the host in the network (HostID). There are also software solutions for changing the MAC address.Īn Internet Protocol ( IP) address is an identification number permanently or temporarily assigned to each device connected to a computer network using the Internet Protocol. !!! abstract Warning This last statement is nowadays a little less true with virtualization. It is composed of : 3 bytes of the manufacturer identifier and 3 bytes of the serial number. It consists of 6 bytes often given in hexadecimal form (for example 5E:FF:56:A2:AF:15). This is sometimes referred to as the hardware address. It is used to broadcast information to all the machines on the network.Ī MAC address is a physical identifier written in the factory onto the device. The last address of a range is the broadcast address. It is used to identify networks and to route information from one network to another. The first address of a range is the network address. The first address of a range as well as the last one have a particular role: There are also specific addresses within a network, which must be identified. the host address ( HostID) by performing a bitwise logical AND between the IP address and the complement of the mask.the network address ( NetID or SubnetID) by performing a bitwise logical AND between the IP address and the mask.The subnet mask is a set of 4 bytes intended to isolate: ![]()
