Study Notes
IP Addressing - IPv4/IPv6
- An IP address is crucial for devices on a network using the Internet Protocol, identifying and locating them.
- The global IP address space is managed by the Internet Assigned Numbers Authority (IANA) and five regional registries (RIRs).
- Two main versions of IP addressing exist: IPv4 (common) and IPv6 (future).
- IPv4 addresses are 32 bits, limiting the address space to about 4.29 billion unique addresses.
- Certain IPv4 addresses are reserved for special purposes (private networks, multicast addressing).
- IPv4 addresses are represented in dotted-decimal notation (e.g., 172.16.254.1).
- Each number in the dotted decimal notation (4 numbers separated by dots) represents 8 bits, totaling 32 bits.
- IP networks can be divided into sub-networks.
- A subnet mask defines how an IP address is divided into network and host parts.
- Private IP addresses are used in networks that don't directly connect to the internet.
- Specific ranges of IP addresses are designated as private (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
- These are used within a network, not directly on the internet.
- IPv6 addresses use 128 bits, significantly expanding the available address space.
- IPv6 addresses are represented in hexadecimal format, using colons to separate groups of hexadecimal digits (e.g., 2001:0DB8:AC10:FE01::).
- IPv6 uses a simpler header structure
- The omission of leading zeros is allowed in IPv6 addressing.
- Four consecutive zero bits in an IPv6 address can be compressed to '::'.
- IPv4 and IPv6 are not directly compatible. Transition methods exist (dual stack, tunneling).
- Dual Stack Method allows IPv4 and IPv6 to coexist on the same networks.
- Tunneling encapsulates IPv6 packets within IPv4 packets to allow IPv6 communication through IPv4 networks
- Translation methods (NAT64, SIIT) are used to bridge IPv4 and IPv6 networks
