Understanding TCP/IP addressing and subnetting basics
Boson TCP/IP Cheat Sheet www.boson.com Subnetting Study Guide by Boson Software, LLC An octet is a binary number of 8 bits, with the lowest possible number being 00000000 and the highest possible number being 11111111, or 28. The binary number 11111111, or 28, converts to 255 in decimal format. Table Address Class Summary Private IP Addresses. RFC 1918 requests that organizations make use of the private Internet address space for hosts that require IP connectivity within their enterprise network, but do not require external connections to the global Internet. For this purpose, the IANA has reserved the following three address blocks for private internets: 10.0.0.0/8 Mar 29, 2019 · Similarly, a device with IP address 193.2.4.5 was able to identify 193.2.4.0 as the network while 0.0.0.5 is the host ID. As the Internet grew, this method of IP addressing resulted in a lot of wastage. For example, an organization that needs only 2 IP addresses will get a Class C address block.

Understand IP Addresses An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits). Subnet Mask Cheat Sheet - kthx.at
