The first and last IP address on each network.
e.g. In a classful class C network, the IP addresses x.x.x.0 and x.x.x.255 are invalid and cannot be assigned to a network interface card.
x.x.x.0 is the network address for the subnet.
x.x.x.255 is the network broadcast address for the subnet.
What else can I help you with?
How many addresses in class c?
A Class C address has a subnet mask of 255.255.255.0, which allows for 256 total IP addresses (from 0 to 255) in each subnet. However, two addresses are reserved: one for the network address and one for the broadcast address. This means there are 254 usable addresses in a Class C subnet.
How will you break a subnet into two smaller subnets?
To break a subnet into two smaller subnets, you need to extend the subnet mask to create additional bits for subnetting. For example, if you start with a /24 subnet (e.g., 192.168.1.0/24), you can change the mask to /25, which divides the original subnet into two subnets: 192.168.1.0/25 (with addresses from 192.168.1.0 to 192.168.1.127) and 192.168.1.128/25 (with addresses from 192.168.1.128 to 192.168.1.255). This effectively doubles the number of subnets while halving the number of usable IP addresses in each new subnet.
What is the maximum number of subnets in class A using this mask of 255.255.192.0?
Ok good question To subnet any network requires borrowing host addresses The 255.255.192.0 regardless of class says host addresses start at CIDR (Classless Inter Domain Routing Protocol) /18. So if we borrow every available host address space then we have 2^14 = 16,384 possible subnet addresses available, NOT. In reality we have 11111111.11111111.11000000.00000000 or a /18 network. Every network / subnet requires two special reserved addresses. The network or zero address, and the last address in the range which will be assigned as the broadcast address. So we can't borrow all of the bits for sub netting. If we only leave one we will only have two addresses for the hosts, this won't work because we need to reserve two. We have to leave two so we will have 2^2 = 4. We can then give each subnet a network address and a broadcast address and still have 2 usable hosts' addresses. If we do this we only have 2^12 subnets = 4096. Each subnet will only have two usable host addresses and two reserved addresses. See the math confirms that 4096 * 4 = 16384 which is the total number of addresses in the address space we started with.
Which device would you use to connect two network segments with different subnet addresses?
A router
Can two Wifi devices communicate directly with each other via WLAN or do they need a router?
Yes, they can. You might want to assign IP addresses manually. They should be in the same subnet.
A network on the internet has a subnet mask 255.255.240.0 what is the maximum number of hosts it can handle?
Convert the subnet mask to binary: 11111111.11111111.11110000.00000000The zeroes tell you which bytes indicate the host; in this case, 12 zeroes allow for 212 = 4096 different IP addresses within the subnet. Of these, two (the first and the last) are unusable for a host, so you have a maximum of 4094 hosts.
How many types of addresses in each network node?
there are two types of addresses: network addresses and physical addresses
What number is the last octet value of 252 in a subnet mask?
In a subnet mask, the last octet value of 252 corresponds to the binary representation of 11111100. This means that the first six bits are used for the network part, while the last two bits are for the host part. Therefore, a subnet mask of 255.255.255.252 allows for only two usable IP addresses within that subnet.
What is a subnet in computer networks?
A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100. would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet mask.
Ate these two computers on the same network IP192.167.222.4 Subnet255.255.555.0 Gateway192.168.222.1 and IP192.168.222.6 Subnet255.255.0.0 Gateway192.167.222.1?
For a start, two computers on the same network should have the same subnet mask. If two computers that are indeed on the same network have different subnet masks, there is a design problem. Now, even if you look only at the last subnet mask - the least restrictive one - the computers are NOT on the same subnet mask. The subnet mask 255.255.0.0 indicates that the first two bytes (or the first 16 bits) of an IP address have to match, to be considered part of the same network. If you look at the IP addresses, this is not the case.
What is the default subnet mask for the IP address 176.43.52.18?
255.0.0.0 for a class A correct. but why? well, 10.10.0.0 is a class a network and all class "a" networks use a default subnet mask of 255.0.0.0. the range of class "a" networks is 1-126.
How do you address to one party at two addresses?
Send two separate letters in separate envelopes, each with their respective addresses.
