Can private IP addresses communicate outside local networks?

Private IP address (Internal) is only used by devices communicating to each other on the same network. Devices with private IP addresses cannot connect to the Internet directly. Likewise, computers or other devices outside the local network cannot connect directly to a device with a private IP.

Which IP address is used to communicate within the network?

Every individual or business with an internet service plan will have two types of IP addresses: their private IP addresses and their public IP address. The terms public and private relate to the network location — that is, a private IP address is used inside a network, while a public one is used outside a network.

Why do we need an IP address to communicate within a LAN?

Computers on a LAN actually do communicate based on MAC addresses. Every packet that goes over Ethernet uses a MAC address. The reason why TCP/IP is used for higher-level communication (Layer 3 in the OSI model) is because it’s a standard that’s universally accessible and also routable between autonomous networks.

How do I communicate with a different IP address?

On a computer network, all devices that are connected to the same local network can talk directly with each other. But to do so they need to have IP addresses that belong to the same IP network. Computers that belong to different IP networks have to communicate with each other via a router.

How do devices communicate in LAN?

Devices on a peer-to-peer local area network share data directly to a switch or router without the use of a central server. LANs can interconnect with other LANs via leased lines and services, or across the Internet using virtual, private network technologies.

Is Network Address same as IP address?

Addresses in computer networks are known as IP addresses. An IP address consists of two components: the network address and the host address. The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet.

What is an outside local address in networking?

Outside local address Outside local address is the real IP address of the end device at other network. Outside local addresses are typically private IP addresses assigned to the computers in the another private network.

Do I need an IP address to communicate with a LAN?

Technically you don’t need an IP address to communicate within a LAN. In fact, when the actual communication takes place IP addresses are only used for looking up MAC addresses and the device won’t send anything out with an IP address on it except under specific circumstances.

How do computers on a LAN communicate with each other?

Computers on a LAN actually do communicate based on MAC addresses. Every packet that goes over Ethernet uses a MAC address. The reason why TCP/IP is used for higher-level communication (Layer 3 in the OSI model) is because it’s a standard that’s universally accessible and also routable between autonomous networks.

What is the difference between inside and outside IP address?

The term inside is used to refer the IP addresses configured inside the network where the user is standing and observing, including the IP addresses of the LAN router. Outside address is any IP address in the public internet, outside the local network. Please refer below image to understand what are inside and outside.
