What is the maximum number of bits that can be borrowed with class b?
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless). A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0 You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
How many bits comprise the network portion of a class c address?
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.
How do you know how many bits represent the network portion and the host portion?
When we express an IPv4 network address, we add a prefix length to the network address. The prefix length is the number of bits in the address that gives us the network portion. For example, in 172.16.4.0 /24, the /24 is the prefix length - it tells us that the first 24 bits are the network address. This leaves the remaining 8 bits, the last octet, as the host portion.
What is the combination of additional bits used for subnet information plus the existing network ID called?
It depends on the book, but is usually known as the extended network prefix.
What is specified by the host bits in an IP address?
The network part of an IP address indicates the network to which the host belongs. The host bits or host part of an IP address points to the actual device that has an IP address on the network. It can be a computer, printer, router or any device with an IP address that has the same network part.
How do you calculate the virtual address space for a given system?
To calculate the virtual address space for a given system, you need to determine the number of bits used for addressing in the system's memory architecture. The virtual address space is typically 2 raised to the power of the number of bits used for addressing, which gives you the total number of unique memory addresses that can be accessed by the system.
Within a classful addressing subnet mask the bits indicate that corresponding bits in an IPv4 address contain network information?
the 1 bits
Which class ip address uses 8 bits for the network id and 24 bits for the host id?
class A
What is used to specify which bits of an ipv4 address are used for the network identifier and which bits are used for the host identifier?
Subnet Mask
How many network and host bits are available in ipv4?
In IPv4, there are a total of 32 bits in an IP address. The number of network and host bits varies depending on the subnet mask used. Typically, the first part of the bits represents the network portion, while the remaining bits represent the host portion. For example, in a common subnet mask of 255.255.255.0 (or /24), there are 24 bits for the network and 8 bits for hosts.
What does net mean for an internet address?
When people refer to internet address they mean IP address. This is an address composed of 4 sections separated by periods. There is a associated network mask. The Network mask tells you which of the bits of the IP address refer to the Network, and so which bits refer to the device. Example 192.168.100.0 with a mask of 255.255.255.0 means that only the 4th part is the device address whereas 192.168.100 is the network. This is a class C address which can have 254 devices. It follows that if you don't know the network mask you can't say which part of the IP address is the network!
What is the valid ip address with network number 190.254.0.0 using 11 bits?
This assumes you know how to subnet. On a network with 190.254.0.0 as a host address and using 11 bits for the subnet mask. The network address is 190.224.0.0 and the end of the range is 190.255.255.224. The address you show is within this range so cannot be the network address. If you don't know how to work this out manually use a subnet calculator such as the one on this URL: http://www.boson.com/FreeUtilities.html
