Study Notes
IP Addressing - IPv4/IPv6
- An Internet Protocol address (IP address) identifies devices on a network, crucial for communication. It's managed globally by IANA and regional registries.
- Two main versions exist: IPv4 (commonly used) and IPv6 (the next version).
- IPv4 addresses are 32 bits, limiting the address pool to roughly 4.29 billion. Some addresses are reserved for specifics like private networks or multicast addressing.
- IPv4 addresses are presented using a dotted-decimal notation (e.g., 172.16.254.1). Each number ranges from 0 to 255.
- Networks can be divided into subnetworks. An IP address has two parts: a network prefix (high-order bits) and a host identifier (the remainder). The subnet mask defines this division.
- Private addresses are used for networks not directly connected to the internet. Special address ranges are reserved for this purpose (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
- The IANA reserves specific IP address blocks for private networks.
- IPv4 private addresses are allocated by the Railway Board for IR data networks.
- Public IP addresses are required for intranet services accessible to the public via the internet.
- Private IPs within the same network must be unique.
- Private IPs cannot access internet services without translation.
- Internet Service Providers (ISPs) manage Internet access, traffic routing, and resolving domain names.
- IPv6 addresses are 128 bits, enabling a dramatically larger address pool (2^128).
- IPv6 has improved security features, including IPSec for protocol security.
- IPv6 headers are simpler than IPv4 headers, making transmission faster.
- Stateless address auto-configuration allows hosts to automatically obtain IPv6 addresses without a DHCP server.
- IPv6 and IPv4 are incompatible; migration strategies are required.
- Dual-Stack is a method where both IPv4 and IPv6 coexist on the same device and network.
- Tunneling encapsulates IPv6 traffic within IPv4 packets, enabling communication through existing IPv4 infrastructure.
- Translation methods like SIIT and NAT64 translate between IPv4 and IPv6 networks.
