how many bits are there in an ip addresss
32 bits
whawt is the decimal range for each octet
0 to 255
where the network part ends and the host part begins depends on the __________-
subnet mask
why is a subnet mask used
A subnet mask is a separate 32-bit pattern that defines an address’s network and host portion.
The subnet mask only tells you where to look for the host and network portion in an IP address and does not actually contain the host or network portion of the IP address.
network portion is to the _______ side of ip address
left
host portion is to the _______ side of ip address
right
Subnet masks do not have to end on “natural octet boundaries”
True
what happens if there is all 0 in the host portion
it is the network address
whatw happens if there is 0s and 1s in host portion
it is host address
all 1s in the hsot portion
broadcast address
what does dhcp stand fo r
dynamic host configuration protocol
why is dhcp used
it is the preferred method of assigning IPv4 addresses to hosts on large networks because it reduces the burden on the network support staff and virtually eliminates entry error s
A private IP address range is allocated for exclusive use to a particular organization by IANA or ICANN.
False
what is multicast address
refers to one of a block of addresses reserved for use in sending the same message to multiple interfaces or nodes
ip address for loopback address
127.0.0.1
