Consider the following non-default subnet masks: (a) 255.255.248.0, (b) 255.128.0.0 . To which IP address class do they pertain?Write down the following in CIDR notation: (a) IP: 150.160.170.180, Subnet Mask:255.255.224.0; (b) IP: 75.80.85.90, Subnet Mask: 255.252.0.0 Three stations A, B, C and D are connected to a common Ethernet hub. Their IPaddresses and subnet mask are respectively: 200.100.50.67, 255.255.255.252;200.100.50.7, 255.255.255.248; 200.100.50.138, 255.255.255.240 and 200.100.50.1,255.255.255.254. Determine which among these stations can communicate with eachother. You need to show all detailed workings.
A network configuration of a modem is given as following:LTE interface IP = 77.110.156.22 MASK 255.255.252.0Default GATEWAY = 77.110.156.1Masquerade NAT, and DNS address = 1.1.1.1Local IP setup: 192.168.128.1 MASK 255.255.255.0And, ip route 192.168.128.0 255.255.252.0 192.168.128.254 Devices numbered R1, R2, R4, R5 are routers. PC is a computer.Image of network with interface names such as f1/0 are added. You must use only static IP addreses and static IP routes to configure the network and make PC able to connect (ping) to Modem.
An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most signi cant bits are used as a network ID, and the 16 least signi cant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?
For example, let say that your Network 1 needs 30 hosts and you are in a class C network, you would start with 192.168.0.1 till 192.168.0.32 because the closest you can get to 30 that is more is 32 (2exp5) so my begin address would be 192.168.0.1, end address would be 192.168.0.32 (not 192.168.0.30 because we only need 30 hosts) and subnet mask would be 255.255.255.224. The next range will start at 192.168.0.33!!! Use the example to answer: We are going to use the private range for a class A network. What is its standard subnet mask? A) Network 1 needs 250 hosts B) Network 2 needs 230 hosts
49- An organization currently requires 40 hosts for its sales department. Given the IP Address 194.12.1.0 /24, design an optimal address scheme usingTradition Subnetting method, which will enable the connection of the sales department’s 40 hosts in one subnet and uses the remaining subnets for other departments’ hosts in the future. What will be the last host address of 4th subnet? Select one: A. 194.12.1.254 B. 194.12.1.192 C. 194.12.1.253 D. 194.12.1.255
so given two printer, one of IP address is 200.23.16.202 and subnet mask is 255.255.255.224, and other one IP address is 200.23.16.170 and subnet mask is 255.255.255.224. Suppose the network that hosts the above printer is re-configured with other networks in the building. After re-configuration, the printer's IP address would remain the same but its network is changed with a new subnet mask, which is changed to 255.255.255.128. This means, even the printer's IP address looks the same, its network ID and host ID are different from those before re-configuration. Find the new network ID and host ID of this printer. You must write both in the standard dot-decimal format without attaching the subnet mask.
An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?
Addresses starting with fe80 are called link-local IPv6 addresses. True or false
. Assume: Your laptop's Ethernet address is 0a:0b:0c:0d:0e:0f, DHCP server address is 131.111.7.3, your IPv4 address will be 131.111.7.121, the gateway's IP address is 131.111.7.1, and Ethernet address is 00:01:02:03:04:05, the network subnet mask is 255.255.255.0.Write the series of protocol/packet exchanges that occur on the wired Ethernet link, up until you can send a single packet to 128.232.0.20. You do not need to describe packets after this packet has left the link. Include ARP and DHCP
What does the "slash-decimal" notation (for example, 1090:9:900:210D:100:100:227:32F / 60) that can follow an IPv6 address denote? (choose one) a number of bits in the network portion of the address b. number of bits in the subnet mask portion of the address c. number of bits in the host portion of the address d. number of bits in the multicast scope identifier
q41- An organization currently requires 40 hosts for its sales department. Given the IP Address 194.12.1.0 /24, design an optimal address scheme usingTradition Subnetting method, which will enable the connection of the sales department’s 40 hosts in one subnet and uses the remaining subnets for other departments’ hosts in the future. Based on the designed address scheme, answer the question 41 – 50How many bits were borrowed for subnetting? Select one: A. 2 B. None of the above C. 4 D. 3
Given the MAC address of an interface is F3:22:1F:20:30:40, what IPv6 link local address would be generated? a. FE80::F122:1FFF:FE20:3040/64 b. FE80::F322:1FFF:FE20:3040/64 c. FE80::F122:1F20:FFFE:3040/64 d. FE80::D322:1F20:FFFE:3040/64
