How is an IPv4 address represented?
An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IPv4 address. This form of representing the bytes of an IPv4 address is often referred to as the dotted-decimal format.
Where are IPv4 address to layer 2?
Where are IPv4 address to Layer 2 Ethernet address mappings maintained on a host computer? Answers Explanation & Hints: The ARP cache is used to store IPv4 addresses and the Ethernet physical addresses or MAC addresses to which the IPv4 addresses are mapped.
Where does a PC store its IPv4 address and MAC address mapping?
1.6. It’s on this network.” Your router will have an internal table called an ARP cache. This table holds a mapping of IP addresses to physical MAC addresses.
How do I give an IPv4 address?
Adding a Public IPv4 Address to the Windows Server
- Open the Control Panel.
- Click Network and Internet > Network and Sharing Center > Change Adapter Settings.
- Right-click the network adapter.
- Click Properties.
- Double-click Internet Protocol Version 4 (TCP / IPv4) .
What are the three types of IPv4 addresses?
IPv4 addresses are categorized into three basic types: unicast address, multicast address, and broadcast address. IPv6 addresses are categorized into three basic types: unicast address, multicast address, and anycast address.
What address is found or used at Layer 2?
MAC address
The MAC address is a layer 2 (data link) address.
What IPv4 header field identifies the upper layer protocol carried in?
What IPv4 header field identifies the upper layer protocol carried in the packet? Explanation: It is the Protocol field in the IP header that identifies the upper-layer protocol the packet is carrying. The Version field identifies the IP version. The Differential Services field is used for setting packet priority.
What are MacMac addresses used for in the IP protocol?
MAC addresses are used during the IP packet encapsulation. IP relies on upper layer services to handle situations of missing or out-of-order packets.* Explanation: IP protocol is a connection-less protocol, considered unreliable in terms of end-to-end delivery.
Does a default gateway address provide Layer 3 routing?
A default gateway address on a switch does not provide Layer 3 routing for PCs that are connected on that switch. A switch can still be accessible from Telnet as long as the source of the Telnet connection is on the local network. 11. What is a basic characteristic of the IP protocol?
Who can get a public IPv6 network address?
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large. The problems that are induced by NAT applications are solved because the IPv6 header improves packet handling by intermediate routers.
