An IP address must be unique within a LAN; the combination of the network and host portion must present a number that is not duplicated anywhere else in the network. Outside of a LAN the IP addresses do not have to be unique, except that the network id portion can only be used by the organization that owns the IP network address. The host portion does not need to be unique across all LANs within an enterprise network.
IP Address
The computer's MAC address must be unique, and the internal IP address must be unique. Either of these being the same as another computer's causes issues which won't let your computer connect.
One computer must have unique MAC addresses for each Ethernet adapter (ideally each Ethernet adapter in existence has a unique MAC address but there are some that allow manual setting of the MAC, so duplicates can exist.) If you have not changed anything from the factory settings then each network card will have a unique address!
Each IP address must be unique within the local network.
you have to have wifi . in order to have wifi , you must be conneted to wireless internet nearby . to get to that = settings>wifi>choose a network
No. Each computer has to have a unique name on the network (example: Desktop-John, Desktop-Matt, Laptop-Kim)
ip address
If you are referring to a flat network protocol such as NetBEUI, the problem in a large network is that the device names must be unique (up to 15 characters). In a large network there is a good chance of attempted duplication of the name, which is not allowed. For example, if a device is called "john" in the network, then no other device could have that name. It would have to be "john1" or something that makes it unique.
One can change the DNS server settings on their computer by right clicking on "My Network Places" button on their computer. After that, one must click on properties. Once there, find the network associated with your internet connection and and right click to change the IP address.
The requirements to make a peer to peer network are you need a unique name for each computer, a similar network protocol, and supported cabling by the network cards. The computers must have a way to communicate with each other.
Yes, all devices on a network must have a unique IP address or you will have an IP conflict and one of the devices will have its network connection disabled.
