Which of the following situations requires sending an ARP request message
The IP address block assigned by a company to the personnel department is 10.0.11.0/27, the IP address block assigned to the planning department is 10.0.11.32/27, and the IP address block assigned to the Marketing Department is 10.0.11.64/26. Then the addresses of these three address blocks after aggregation are
In the autonomous system using RIP protocol, if router R1 receives neighbor router R2 and sends it to the distance vector containing , then it can be concluded that
If both the destination network and the destination host are correct, but the IP packet is carrying TCP packets, and the destination host is using UDP protocol. Then, what type of ICMP packet will the destination host sends to the source host after dropping the packet

The IP address space of a network is 201.1.5.0/24, which is divided by subnet, and the address mask is 255.255.255.248. Then, the maximum number of subnets and the maximum number of addresses that can be allocated for each subnet of the network are
If the subnet mask is 255.255.192.0, which host with the following addresses must be routed to communicate with host 128.2.144.16
A company has the IP address 201.12.77.0/24, among which 201.12.77.16/28 and 201.12.77.32/28 have been assigned to the personnel department and finance department. Now the technical department needs 100 IP addresses, and the addresses that can be assigned are
R1 and R2 are two adjacent routers using RIP routing protocol in an autonomous system. The routing table of R1 is shown in figure (a). As shown in figure (b), R1 receives the (V, D) message sent by R2, and the distance of the four routing table items of R1 after the update is 0, 4, 4, and 2 from top to bottom. So the possible data among a, b, c, and d in figure (b) may be ( )
