Types of IP Addresses

IPv4 (Internet Protocol version 4):

Composed of four numbers separated by dots (e.g., 192.168.1.1).

IPv4 supports approximately 4.3 billion unique addresses.

IPv6 (Internet Protocol version 6):

Introduced to address the limitations of IPv4 due to the growing number of devices.

Utilizes a larger address format (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

Offers virtually unlimited unique addresses and improved efficiency.

Categories of IP Addresses

Public IP Address:

Private IP Address:

Assigned to devices within a local network, such as a home or office.

Used for internal communication and cannot be accessed directly from the internet.

Static IP Address:

Fixed and does not change over time.

Often used for servers or devices that require consistent accessibility.

Dynamic IP Address:

Changes periodically and is assigned by a DHCP (Dynamic Host Configuration Protocol) server.

Commonly used for residential internet connections.
