IPv6 Addressing - Unicast Addressing

What is Unicast Addressing?

Unicast addressing is a method of communication where data is sent from one source device to one specific destination device over a network.

Why is Unicast Addressing useful?

Unicast is the most common form of network communication. It is efficient for one-to-one data exchanges like web browsing, file transfers, and emails.

How it works?

In unicast communication, each packet contains the unique IP address of the destination device. Routers forward the packet based on this address to reach the correct recipient.

Where is Unicast Addressing used?

Unicast is used in most standard internet and network communications, including HTTP, FTP, SSH, VoIP, and more.

Which OSI layer does this protocol belong to?

Unicast addressing operates at the Network Layer (Layer 3) of the OSI model, using IP for addressing and routing.

Is Unicast Addressing Windows specific?

No, unicast addressing is not Windows specific. It is universally supported across all platforms that implement the IP protocol.

Is Unicast Addressing Linux specific?

No, unicast addressing is not Linux specific. It is supported by all network-capable operating systems, including Linux, Windows, and macOS.

Which Transport Protocol is used by Unicast Addressing?

Unicast can use both TCP and UDP transport protocols depending on the application requirements.

Which Port is used by Unicast Addressing?

Unicast addressing itself does not define any specific port. The port number depends on the application or service being used (e.g., HTTP uses port 80).

Is Unicast Addressing using client-server model?

Yes, unicast is often used in client-server communication, where a client sends requests to a specific server, and the server responds directly to that client.
