Quick Answer: What Is The Destination IP Address When An IPv4 Host Sends A Dhcpdiscover Message?

Why are routers needed in networking?

Features of Routers It connects different networks together and sends data packets from one network to another.

A router can be used both in LANs (Local Area Networks) and WANs (Wide Area Networks).

It transfers data in the form of IP packets..

Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address group of answer choices?

255.255. 45. Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address? Explanation: The show ip dhcp binding command will show the leases, including IP addresses, MAC addresses, lease expiration, type of lease, client ID, and user name.

What kind of message is sent by a DHCP client when its IP address lease has expired?

DHCPREQUEST unicast message​ Explanation: When the IP address lease time of the DHCP client expires, it sends a DHCPREQUEST unicast message directly to the DHCPv4 server that originally offered the IPv4 address.

What is the most likely scenario in which the WAN interface of a router would be configured as a DHCP client to be assigned a dynamic IP address from an ISP?

The router is configured for stateless DHCPv6 operation. What is the most likely scenario in which the WAN interface of a router would be configured as a DHCP client to be assigned a dynamic IP address from an ISP? it is a SOHO or home broadband router. Match the DHCP message types to the order of the DHCPv4 process.

Under which circumstance would a router usually be configured as a DHCPv4 client?

Under which two circumstances would a router usually be configured as a DHCPv4 client? It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information. A network administrator configures a router to send RA messages with M flag as 0 and O flag as 1.

Why does a Layer 2 switch need an IP address?

A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface.

Is IP private?

In IP networking, a private network is a computer network that uses private IP address space. … Private network addresses are not allocated to any specific organization. Anyone may use these addresses without approval from regional or local Internet registries.

Which message does an IPv4 host use to reply when it receives a Dhcpoffer?

Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server? When the client receives the DHCPOFFER from the server, it sends back a DHCPREQUEST broadcast message.

Which IP address is a valid network address?

An IP address is a set of numbers that identify your computer on a network. IPV4, the traditional numbering scheme, uses four integers ranging from zero to 255 and set apart by periods. For example, “204.120. 0.15” is a valid IPV4 address.

What is involved in an IP address spoofing attack?

In an IP address spoofing attack, an attacker sends IP packets from a false (or “spoofed”) source address in order to disguise itself. Denial-of-service attacks often use IP spoofing to overload networks and devices with packets that appear to be from legitimate source IP addresses.

What are three characteristics of multicast transmission choose three?

A single packet can be sent to a group of hosts. Multicast transmission can be used by routers to exchange routing information. Multicast transmission can be used by routers to exchange routing information. Multicast transmission can be used by routers to exchange routing information.

Which layer 2 attack will result in legitimate users not getting valid IP addresses?

What is the result of a DHCP starvation attack? The attacker provides incorrect DNS and default gateway information to clients. The IP addresses assigned to legitimate clients are hijacked. Clients receive IP address assignments from a rogue DHCP server.

What are the four primary message types used with DHCPv6?

Four types are identified in RFC 8415:Link-layer address plus time (DUID-LLT)Vendor-assigned unique ID based on enterprise number (DUID-EN)Link-layer address (DUID-LL)UUID-based DUID (DUID-UUID)

What is the reason why the Dhcprequest message is sent as a broadcast during the DHCPv4 process?

What is the reason why the DHCPREQUEST message is sent as a broadcast during the DHCPv4 process? To notify other DHCP servers on the subnet that the IP address was leased. To notify other DHCP servers on the subnet that the IP address was leased.

What is the reason that an ISP commonly assigns a DHCP?

The IP address between the wireless router and ISP site is typically assigned by the ISP through DHCP. This method facilitates the IP addressing management in that IP addresses for clients are dynamically assigned so that if a client is dropped, the assigned IP address can be easily reassigned to another client.
