SLAAC - statless address autoconfiguration.

SLAAC allows for automatic iP addresses without DHCP. Forsterr self sufficency and reduce administrative overhead of adding IP addresses.

5 setp process.

Domain Name System - DNS - helps resolve a hostname from an ip address. convetrts name to numbers and numbers to names.

Fully-Qalified Domain Name - when a domain name is with a top level provider.

Root - answer requests in the root zone

top level domain com .net .uk

second-level domain jimi421.com

subdomain blog.jimi421.com, mail.jimi421.com

host - refers to a specefic machine

URL - uniform resource locator.

Host file - simple text file taht servs as the first point of contact when a device wants to seek out communication with another device on a network.

Malicious attackers can exploit this.

SLAAC (Stateless Address Autoconfiguration) – IPV6

  • Allows devices to self-assign IPV6 addresses without DHCP.
  • Reduces admin overhead → plug-and-play networking.
  • Works with Router Advertisements (RA).

5-Step SLAAC Process:

  1. Device Init – Generates temporary link-local address.
  2. Router Solicitation – Device asks local routers for info.
  3. Router Advertisement – Router provides network prefix.
  4. Address Configuration – Device combines prefix + unique ID (often EUI-64 from MAC).
  5. Duplicate Address Detection – Device checks for conflicts before finalizing.

Exam Tip: SLAAC = IPV6 self-config, DHCP not required.
