Identify the Following Address Formats
IPv4 – Every IP address can be broken down into 2 parts, the Network ID(netid) and the Host ID(hostid). All hosts on the same network must have the same netid. Each of these hosts must have a hostid that is unique in relation to the netid. IP addresses are divided into 4 octets with each having a maximum value of 255. We view IPv4 addresses in decimal notation such as 220.127.116.11, but it is actually utilized as binary data.
IP addresses are divided into 3 classes as shown below:
NOTE: 127.x.x.x is reserved for loopback testing on the local system and is not used on live systems. The following address ranges are reserved for private networks:
10.0.0.0 – 10.254.254.254
172.16.0.0 – 172.31.254.254
192.168.0.0 – 192.168.254.254
IPv6 – The previous information on TCP/IP has referred to IPv4, however, this addressing scheme has run out of available IP addresses due to the large influx of internet users and expanding networks. As a result, the powers that be had to create a new addressing scheme to deal with this situation and developed IPv6. This new addressing scheme utilizes a 128 bit address (instead of 32) and utilizes a hex numbering method in order to avoid long addresses such as 18.104.22.168.22.214.171.124.126.96.36.199.188.8.131.52. The hex address format will appear in the form of 3FFE:B00:800:2::C for example.
MAC Addressing – Also known as hardware address or ethernet address, A MAC address is a unique code assigned to most networking hardware. The hardware is assigned a unique number by the manufacturer and the address is permanently assigned to the device. MAC Addresses are in a 48-bit hexidecimal format such as 00:2f:21:c1:11:0a. They are used to uniquely identify a device on a network, and for other functions such as for being authenticated by a DHCP server.
