VLAN Name Status Ports I’ve already said that when IPv4 was devised, the Internet wasn’t used by the These are all Class A addresses because they are within the range of 1 to 126. 127 is not a permitted number for IP addresses; 127.0.0.1 is actually an 172.16.1.8, and keep counting up to 172.16.20.0 Repeat the test using EUI-64 addresses (IPv6 address 2001::/64 eui-64) Hard code an interface Link-Local address: IPv6 address fe80:1234:abcd:1::3 Link-Local Clock mux=0x30, ucmd_ctrl=0x0, port_status=0x1 line state: down Firstly, write out all of the network addresses in full and then the binary versions to the right of that, as illustrated below: Delving into binary math, you can see that using the first two bits of the host address lets you use the binary combinations 00, 01, 10, and 11, and writing these out in full, as you see in the subnets column, gives you the subnets 0, 64, 128, and 192. To clarify this further, the first two rows in gray are subnet numbers and the remaining six rows are for use by host numbers on each subnet. The Presentation Layer presents data to the Application Layer. Multimedia works here, so think MP4, JPEG, GIF, etc. Encryption, decryption, and data compression also take place at this layer. Slicing Down Networks Wireless Networking and Components While the preferred form or representation is the most commonly used method for representing the 128-bit IPv6 address in text format, it is also important to be familiar with the other two methods of IPv6 address representation. These methods are described in the following sections. Anycast,ccna 200 301 book pdf free download, which was introduced earlier in this section, can be described simply as one-to-nearest communication, because the nearest common address, based on routing protocol metrics, will always be preferred by the local device. In IPv6 there is no specially allocated range for Anycast, as Anycast addresses use Global Unicast, Site-Local, or even Link-Local addresses. However, there is an Anycast address reserved for special use. This special address is referred to as the Subnet-Router Anycast address and is formed with the subnet’s 64-bit Unicast prefix, with the remaining 64 bits set to zero (e.g., 2001:1a2b:1111:d7e5:0000:0000:000:0000). Anycast addresses must not be used as the source address of an IPv6 packet. These addresses are typically used by protocols such as Mobile IPv6, which is outside the scope of the CCNA.
