Subnet Mask: Subnet mask is a 32 bits value which differentiate the host portion & network portion of an IP address. Where network portion is designate by the 1's & host portion 0's. Wild card Mask: Wild card mask defines which IP addresses are allowed & which are blocked. Where 0's defines the accurate match where non zero value defines any value on the corresponding octete.
An IP number is the unique address by which you can reach an individual computer. At least, that was the original idea of IP addresses; if you want to know how this has changed in recent days, do some research on the following topics: IP address exhaustion; private IP addresses; public IP addresses; NAT.
ip adress
This is not a valid IP address - a valid IP address has 4 bytes. Also, you can't guess the subnet mask from looking only at the IP address; there are usually several options.
223.1.3.27
Host ID
I would say it resembles a network ID because no individual computer can have an IP address that ends with 0 because that's reserved for the...network ID.
It represents the network portion
Which portion of the destination IP address is used as a packet is routed through the Internet?
host portion.
All of it.
the network portion of the destination ip address
An "ip address" is a complete source or destination address that has a network id portion and a client or host portion. The network id is just a piece of the IP address. So, a public ip is an IP address that can be routed, whereas the network id is just a part of the public ip. They aren't different; the network id is part of the ip address.
Seeing as the IP address of 128.107.10.11 is a class B network, the host portion is 10.11
no
no
The host portion of an IP address of all zeros indicates that you are referring to 'this network'. For example, the address 145.5.0.0 means the network 145.5
