Explain:An IPv4 address is made up of 4 octets of binary digits, every containing 8 bits, causing a 32-bit address.
Explain:An IPv4 resolve is separated into 2 parts: a network portion – to recognize the particular network on i m sorry a organize resides, and also a host section – to identify certain hosts on a network. A subnet mask is provided to recognize the length of each portion.
Explain:The /24 mirrors that the network attend to is 172.17.4.0. The broadcast deal with for this network would certainly be 172.17.4.255. Useable host addresses because that this network room 172.17.4.1 with 172.17.4.254.
to uniquely recognize a hold on a networkto identify whether the resolve is windy or privateto identify the subnet come which the hold belongs*to mask the IP resolve to outsiders
Explain:With the IPv4 address, a subnet mask is additionally necessary. A subnet mask is a special form of IPv4 attend to that coupled v the IP deal with determines the subnet of i m sorry the maker is a member.
Explain:The cut notation /20 to represent a subnet mask v 20 1s. This would translate to: 11111111.11111111.11110000.0000, which in turn would convert into 255.255.240.0.
Explain:A directed transfer is a article sent to every hosts ~ above a certain network. That is valuable for sending out a transfer to every hosts ~ above a nonlocal network. A multicast article is a article sent to a selected team of hosts that are component of a subscribing multicast group. A minimal broadcast is supplied for a interaction that is minimal to the master on the regional network. A unicast blog post is a message sent from one hold to another.
The resource address the a multicast infection is in the variety of 18.104.22.168 to 22.214.171.124.A single packet have the right to be sent to a team of hosts. *Multicast transmission deserve to be offered by routers to exchange routing information. *The selection of 126.96.36.199 to 188.8.131.52 is booked to reach multicast groups on a neighborhood network.*Computers usage multicast infection to request IPv4 addresses.Multicast message map reduced layer addresses to top layer addresses.
Explain:Broadcast message consist of solitary packets that are sent out to every hosts ~ above a network segment. These species of messages are offered to inquiry IPv4 addresses, and map top layer addresses to lower layer addresses. A multicast infection is a single packet sent to a group of hosts and is used by routing protocols, such together OSPF and RIPv2, to exchange routes. The address variety 184.108.40.206 to 220.127.116.11 is scheduled for link-local addresses to reach multicast groups on a regional network.
Explain:The personal IP addresses room within these three ranges:10.0.0.0 – 10.255.255.255172.16.0.0 – 172.31.255.255192.168.0.0 – 192.168.255.255
9. Which two IPv4 come IPv6 change techniques control the interconnection that IPv6 domains? (Choose two.)
Explain:There space three techniques to permit IPv4 and IPv6 come co-exist on a network. Double stack allows IPv4 and also IPv6 come coexist ~ above the exact same network segment. Dual stack devices run both IPv4 and IPv6 protocol stacks simultaneously. Tunneling is a an approach of transporting an IPv6 packet over an IPv4 network. The IPv6 packet is encapsulated within an IPv4 packet, comparable to other varieties of data. Network deal with Translation 64 (NAT64) allows IPv6-enabled tools to connect with IPv4-enabled gadgets using a translation technique similar come NAT for IPv4
10. I beg your pardon of this addresses is the shortest abbreviation because that the IP address:3FFE:1044:0000:0000:00AB:0000:0000:0057?
11. What form of attend to is automatically assigned come an user interface when IPv6 is allowed on that interface?
Explain:When IPv6 is allowed on any kind of interface, that interface will automatically generate an IPv6 link-local address.
Explain:Multicast, anycast, and also unicast are varieties of IPv6 addresses. There is no broadcast deal with in IPv6. Loopback and link-local room specific types of unicast addresses.
an user interface ID the is offered to determine the regional network because that a specific hosta an international routing prefix the is provided to determine the network part of the attend to that has been detailed by one ISP *a subnet ID that is provided to determine networks inside of the local enterprise site*a worldwide routing prefix the is supplied to determine the portion of the network address listed by a regional administratoran interface ID the is used to determine the local host on the network*
Explain:There room three facets that make up an IPv6 worldwide unicast address. A global routing prefix i m sorry is noted by one ISP, a subnet ID i beg your pardon is determined by the organization, and an interface ID which uniquely identifies the user interface interface that a host.
14. An administrator desires to configure master to instantly assign IPv6 addresses to themselves by the usage of Router advertising messages, but also to achieve the DNS server address from a DHCPv6 server. Which deal with assignment technique should be configured?
Explain:Stateless DHCPv6 allows clients to usage ICMPv6 Router advertisement (RA) message to immediately assign IPv6 addresses come themselves, however then permits these clients to call a DHCPv6 server come obtain additional information such together the domain surname and address of DNS servers. SLAAC go not permit the customer to obtain added information with DHCPv6, and stateful DHCPv6 requires that the client receive that is interface address directly indigenous a DHCPv6 server. RA messages, when merged with one EUI-64 user interface identifier, are offered to instantly create an interface IPv6 address, and are part of both SLAAC and stateless DHCPv6.
15. I beg your pardon protocol supports Stateless attend to Autoconfiguration (SLAAC) for dynamic assignment the IPv6 addresses come a host?
Explain:SLAAC uses ICMPv6 messages as soon as dynamically assigning one IPv6 address to a host. DHCPv6 is one alternate technique of assigning one IPv6 addresses come a host. ARPv6 does not exist. Neighbor discovery Protocol (NDP) provides the usability of ARP because that IPv6 networks. UDP is the deliver layer protocol offered by DHCPv6.
the variety of routers in between the source and destination devicethe IP resolve of the router nearest the destination devicethe typical time it takes a packet to with the destination and also for the an answer to go back to the source *the destination machine is reachable through the network*the typical time the takes every router in the course between resource and destination to respond
Explain:A ping command offers feedback on the time between when an echo inquiry was sent out to a remote host and also when the echo answer was received. This have the right to be a measure of network performance. A effective ping also indicates that the location host to be reachable v the network.
to educate routers about network topology changesto ensure the distribution of an IP packetto provide feedback the IP packet transmissions*to monitor the procedure of a domain name to IP deal with resolution
Explain:The function of ICMP message is to administer feedback around issues the are pertained to the handling of IP packets.
The host is cabled properly.The default gateway address is appropriately configured.All hosts on the local connect are available.The link-local address is correctly configured.IP is properly set up on the host.*
Explain:The IPv6 deal with ::1 is the loopback address. A successful ping come this address way that the TCP/IP ridge is properly installed. That does not mean that any kind of addresses are effectively configured.
19. A user is executing a tracert come a remote device. In ~ what suggest would a router, which is in the course to the location device, protect against forwarding the packet?
when the router obtain an ICMP Time surpassed messagewhen the RTT value reaches zerowhen the organize responds through an ICMP Echo reply messagewhen the value in the TTL field reaches zero*when the worths of both the Echo Request and also Echo answer messages reach zero
Explain:When a router obtain a traceroute packet, the worth in the TTL ar is decremented by 1. As soon as the worth in the ar reaches zero, the receiving router will not forward the packet, and also will send an ICMP Time gone beyond message earlier to the source.
Explain:ICMPv6 sends a Time Exceeded message if the router can not forward one IPv6 packet because the packet expired. The router provides a hop limit ar to recognize if the packet has actually expired, and does not have actually a TTL field.
Explain:To transform a binary number come the decimal equivalent, add the value of the position where any binary 1 is present.
Explain:To convert a decimal number come binary, first determine if the decimal number is equal to or higher than 128. In this case, because 232 is bigger than 128, a 1 is put in the little bit position because that decimal worth 128 and the value of 128 is then subtracted native 232. This outcomes in the value of 104. Us then to compare this worth to 64. As 104 is larger than 64, a 1 is placed in the little bit position for the decimal value 64 and also the value of 64 is subtracted from 104. The staying value is climate 40. The process should be continued for all the remaining little bit positions.
Explain:To convert from hexadecimal come decimal, multiply each digit by the place value the is connected with the position of the number and include the results.
