RARP
how do you obtain network id from ip address
ARP
ARP
An IP Address, or Internet Protocol Address. Each device has one.
IP address is the internet protocol address which is unique for each system in the given network. IP address is like an unique id that uniquely identifies a system on a network. Yes even if you are not connected to internet, computer would still have an IP address.
internet provider Its actually internet protocol. Every computer on the network has to have its own address, this address is called the IP address. Though since you asked what is IP. IP is just a protocol.
IP (internet protocol)
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
it stands for well sort of like the web so it's like all of the internet just for that network.
Well, an IP address will allow you to get on the internet (Public/External IP address, eg. 203.50.6.14). A MAC Address only comes into action internally in a network, Most notably during the process of DHCP, and APR tables. A MAC address is used to identify machines based on their network cards physical address within a network, where as your Public or External IP address is used to identify you on the internet.
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!
•If the hosts on a network using private IP addresses need to access the Internet, a problem arises because the private IP addresses are not allowed on the Internet. •The solution is to use NAT (Network Address Translation), which uses a single public IP address to access the Internet on behalf of all hosts on the network using other IP addresses.
