|---|---|---|---|---|---|
| Address pool | show 🗑
|
||||
| show | An IPv4 multicast address that is restricted to a local group or organization.
🗑
|
||||
| AND | show 🗑
|
||||
| Broadcast Address | show 🗑
|
||||
| show | An IPv4 addressing scheme that uses a subnet mask that does not follow classful addressing limitations. It provides increased flexibility when dividing ranges of IP addresses into separate networks.
🗑
|
||||
| Classless Addressing | show 🗑
|
||||
| Digital Logic | show 🗑
|
||||
| show | A term that describes IPv4 packets sent to all hosts in a particular network. In a directed broadcast, a single copy of the packet is routed to the specified network, where it is broadcasted to all hosts on that network.
🗑
|
||||
| show | A convention for writing IP addresses with four decimal numbers, ranging from 0 to 255, with each octet (each decimal number) representing 8 bits of the 32 bit IP address.
🗑
|
||||
| show | Unique addresses that are public domain addresses.
🗑
|
||||
| show | The portion of a binary number that carries the most weight, the one written farthest to the left. High-order bits are the 1s in the network mask.
🗑
|
||||
| Internet Backbone | show 🗑
|
||||
| show | As part of the TCP/IP internet layer, ICMP defines protocol messages used to inform network engineers of how well an internetwork is working. Used to troubleshoot nodes via commands like PING and TRACEROUTE.
🗑
|
||||
| Limited broadcast | show 🗑
|
||||
| Limited-scope Addresses | show 🗑
|
||||
| show | An IPv4 address in the range of 169.254.1.0 to 169.254.254.255. Communication using these addresses is used with a TTL of 1 and limited to the local network.
🗑
|
||||
| Loopback | show 🗑
|
||||
| Low-order bits | show 🗑
|
||||
| show | The bit position in a binary number having the greatest value. The most significant bit is sometimes referred to as the leftmost bit.
🗑
|
||||
| Multicast Client | show 🗑
|
||||
| show | A group that receives a multicast transmission. The members of a multicast group have the same IP multicast IP addressing to receive the same transmission (a one to many transmission).
🗑
|
||||
| show | Translation of RFC 1918 addresses to public domain addresses. Allows private IP addresses to masquerade behind a public IP address.
🗑
|
||||
| Network Time Protocol (NTP) | show 🗑
|
||||
| Positional notation | show 🗑
|
||||
| show | In IP subnetting, this refers to the portion of a set of IP addresses whose value must be identical for the addresses to be in the same subnet.
🗑
|
||||
| show | Defined in RFC 1918, an IP address that does not have to be globally unique because the address exists inside a single private IP internetwork.
🗑
|
||||
| Public Addresses | show 🗑
|
||||
| show | The number of various unique digits, including 0, that a positional numeral system uses to represent numbers. For example, in the binary system, (base 2), the radix is 2. In the decimal system (base 10), the radix is 10.
🗑
|
||||
| Regional Internet Registries (RIR) | show 🗑
|
||||
| Reserved link-local addresses | show 🗑
|
||||
| Round-trip Time (RTT) | show 🗑
|
||||
| Scope | show 🗑
|
||||
| show | A method of expressing a network prefix. It uses a forward slash (/) followed by a network prefix such as 192.168.254.0/24. This /24 represents the 24-bit network prefix in slash format.
🗑
|
||||
| show | The IPv4 address block 192.0.2.0 to 192.0.2.255 (192.0.2.0/24) that is set aside for teaching and learning purposes. These addresses can be used in documentation and network examples.
🗑
|
||||
| What subnet mask would be used with the hosts in the 128.107.176.0/22 network? | show 🗑
|
||||
| You have been assigned the address block 10.255.255.224/28 to create the network addresses for PTP WAN links. How many of these WANs can you support with this address block? 1, 4, 7, or 14? | show 🗑
|
||||
| What defines an IPv4 logical network? | show 🗑
|
||||
| show | Network Address: The address by which you refer to the network. Broadcast Address: A special address used to send data to all hosts in the network. Host Address: The addresses assigned to the end devices in the network.
🗑
|
||||
| What distinguishes each of the three types of IPv4 addresses? | show 🗑
|
||||
| show | Unicast: Sending a packet from one host to an individual host. Broadcast: Sending a packet from one host to all hosts in the network. Multicast: Sending a packet from one host to a selected group of hosts.
🗑
|
||||
| show | Specified private addresses allow network administrators to allocate addresses to those hosts that do not need to access the Internet.
🗑
|
||||
| List 3 reasons for planning and documenting IPv4 addresses. | show 🗑
|
||||
| Cite examples where network administrators should statically assign IPv4 addresses. | show 🗑
|
||||
| show | The lack of IPv4 addresses in the future is what spurred IPv6 development.
🗑
|
||||
| What is the purpose of the subnet mask in IPv4 addressing? | show 🗑
|
||||
| show | Grouping based on common geographic location, Grouping hosts used for specific purposes, Grouping base on ownership.
🗑
|
||||
| What are three tests that use the ping utility to test and verify the operation of a host? | show 🗑
