An IPv4 address consists of 4 octets with decimal values ranging from 0 to 255. IP addresses are classified into 5 classes based on the value of the first octet: Class A: Class A addresses are typically used in networks that require a large number of hosts. The first byte of a Class ...
An IPv4 address consists of 32-bit integers. Depending on a network's available addresses or host identifiers, it belongs to one of five classes. IPv4 is still the most common protocol today. However, as the Internet grew, it became apparent that the classful addressing system of IPv4 would...

IPv4 uses 32 binary bits to create a single unique address on the network. An IPv4 address is expressed by four numbers separated by dots. Each number is the decimal (base-10) representation for an eight-digit binary (base-2) number, also called an octet. For example: 216.27.61.137 IPv6...
An IPv4 address is a 32-bit number written in the dotted-decimal notation; that is, as four decimal numbers, one for each byte, separated by three periods.2 For flexibility in network administration and operation, the subnetting technique was introduced, where an IP address is divided into ...
In our example, there is a C-MCAST (Customer Multicast) source with an IPv4 address“192.1.1.1” sending traffic to a C-MCAST group at address “239.1.1.1.” The VPN Group address assigned for this MVPN in the provider network is “239.2.2.2.” Therefore, in Figure 2.33 the customer ...
The prefix length of the network bits in an EUI-64 address must not be longer than 64 bits. EUI-64 addresses, global unicast addresses, or both can be configured on an interface to enable communication. Those configured on the same interface, however, must belong to different network ...
The wildcard mask with the most 0 bits identifies the smallest source IP address range. If the protocol types and source IP address ranges are the same, the rule that defines the smallest destination IP address range is processed. The wildcard mask with the most 0 bits identifies the ...
In many cases, you might connect through an internet service provider (ISP) or from behind your firewall without a static IP address. If so, make sure to determine the range of IP addresses used by client computers. Warning If you use0.0.0.0/0for SSH access, you make i...
Configure this parameter only if you enable IPv4/IPv6 dual stack. Configure an IPv6 CIDR block for Services. You must specify a Unique Local Unicast Address (ULA) space within the address rangefc00::/7. The prefix must be 112 bits to 120 bits in length. We recommend that you spec...
