    Study Notes

    IP Address

    • IP addresses are written in dotted notation, which is converted to dotted decimal notation (e.g., 123.123.123.123).
    • Every port connected to the Internet has a unique IP address.
    • There are two versions of IP addresses: IPv4 and IPv6.
    • IPv4 has a total of 4,294,967,296 (232) possible addresses.
    • IPv6 was introduced to extend the number of IP addresses for future growth.

    IPv4 Address Classes

    • Class A: 1.0.0.1 to 126.255.255.254, with 16 million hosts on 127 networks each.
    • Class B: 128.1.0.1 to 191.255.255.254, with 65,000 hosts on 16,000 networks each.
    • Class C: 192.0.1.1 to 223.255.254.254, with 254 hosts on 2 million networks each.
    • Class D: 224.0.0.0 to 239.255.255.255, reserved for multicasting.

    IP Address Management

    • IP addresses are managed and governed by the International Assigned Number Authority (IANA).
    • Regional registries or authorities for IP distribution include:
      • APNIC (Asia-Pacific region)
      • AFRINIC (Africa region)
      • ARIN (North America and some Caribbean countries)
      • LACNIC (Latin America and some Caribbean countries)

    DNS Server

    • DNS (Domain Name System) is a type of server that converts domain names to IP addresses.
    • DNS is also known as a domain name resolution server or URL (Uniform Resource Locator).
    • DNS servers are used to route data packets between hosts, routers, and DNS servers.
    • DNS servers are linked to 13 root name servers, located in the United States, Stockholm, Tokyo, and Amsterdam.

    DNS Server Hierarchy

    • DNS servers convert domain names to IP addresses.
    • DNS servers are responsible for routing at the backend.
    • Many public DNS servers are available, including Google DNS, OpenNIC, Cloudflare, and Verizon.

    Internet Software Infrastructure

    • Every hardware component of the Internet uses unique software to perform specific tasks.
    • Routers have their own OS for routing, route calculation, filters, and other activities.
    • Switches have their own system software for their respective duties.
    • Servers have their own software applications that run on their OS to cater to client requests.

    Internet Software Infrastructure and Protocols

    • Major software infrastructures and protocols used in the Internet include:
      • IP Address
      • DNS Server
      • TCP/IP Protocol
      • HTTP
      • World Wide Web (WWW)
