internet, your online activity first goes to your ISP and is immediately routed to your device via your IP address. Note that while IPv4 offers a limited number of addresses that can be assigned, this is not the case with IPv6.Hereis an article by HowToGeek exlaining how IP addresses ...
Address block (CIDR) Range Number of addresses Scope Purpose 0.0.0.0/8 0.0.0.0 –0.255.255.255 16,777,216 Software Used for broadcast messages to the current ("this")[1] 10.0.0.0/8 10.0.0.0 –10.255.255.255 16,777,216 Private network Used for local communications within a private network[...
An IP address consists of 32 bits. Instead of expressing IPv4 addresses 32 bits at a time using binary notation (Base2), it is standard practice to segment the 32 bits of an IPv4 address into four 8-bit fields calledoctets. Each octet is converted to a decimal number (base 10) from ...
IPv6 is the solution that addresses the relatively limited number of IP addresses possible under IPv4. Under IPv6, there will no longer be a shortage of the total number of possible addresses. IPv6 allows for a theoretical 340,282,366,920,938,463,463,374,607,431,768,211,456, or 340 ...
Class A network IDs were assigned to networks with a very large number of hosts. The high-order bit in a class A address is always set to zero, which makes the address prefix for all class A networks and addresses 0.0.0.0/1 (or 0.0.0.0, 128.0.0.0). The next seven bits (completing...

There is no limit to the number of IP addresses that can be configured. This setting is useful if this computer connects to a single physical network but requires advanced IP addressing because of either of the following reasons:A single logical IP network is in use and this computer needs ...
