Study Notes
IP Addressing Key Concepts
- Class C private IP address range: 192.168.0.0 to 192.168.255.255.
- IPv6 advantages over IPv4:
- Increased address availability
- Simpler header structure
- Options for authentication and security features.
Automatic Addressing and Unique Identifiers
- APIPA (Automatic Private IP Addressing):
- Assigns addresses starting with 169.254 when DHCP server contact fails.
- Unicast address:
- Assigned to a single interface, facilitating direct communication.
- Multicast address:
- Used for one-to-many communications, permitting efficient data distribution.
MAC and EUI-64 Addressing
- MAC address:
- A 48-bit address physically assigned to network interfaces (NICs).
- EUI-64 format conversion:
- A method used to create IPv6 addresses from a MAC address by inserting 'fffe' in the middle of the address and adjusting the prefix.
IPv6 Address Types
- IPv6 unicast:
- Addresses packets to a single interface.
- Global unicast:
- Functions like a public IPv4 address; routable on the Internet.
- Link-local:
- Not routed; used for communication within a local network segment.
- Unique local:
- Globally unique but not routed on the Internet, previously termed site-local.
- Multicast:
- Delivered to multiple interfaces simultaneously.
- Anycast:
- Delivered to the nearest member of a group of interfaces.
Special Addresses and Ranges
- IPv4 loopback address:
- 127.0.0.1 is used for diagnostics and local testing.
- IPv6 loopback address:
- ::1 serves the same purpose as 127.0.0.1.
- Link-local addresses:
- Always start with FE80::/10.
- Unique local unicast addresses:
- Begin with FC00::/7.
Private and Reserved Address Ranges
- Class B private address range:
- 172.16.0.0 to 172.31.255.255.
- Class C first octet range:
- Decimal: 192-223; Binary: 110xxxxx.
- Addresses not allowed on the Internet:
- The range 172.16.0.0 to 172.31.255.255 is restricted for private use to avoid conflicts in different administrative domains.
DHCP and Automatic Address Configuration
- An inability to contact a DHCP server is indicated by automatic configuration within the range:
- 169.254.0.x with a mask of 255.255.0.0 signifies usage of the link-local address space due to DHCP failure.
