IPv6’s SLAAC lets devices self-configure without DHCP. Hosts send RS, receive RAs (with prefixes/flags), and build their GUA using a unique Interface ID (EUI-64/Privacy). A quick DAD check confirms uniqueness. It’s simple and stateless.

IPv6 addresses come in flavors. Global Unicast, Link-Local, Unique Local, Multicast, Anycast, Loopback, and Unspecified. Each is identified by its binary prefix and hex pattern, making it easy to spot scope, purpose, and reachability at a glance.

IS-IS TLVs define how routing information is shared and covering IPv4, IPv6, traffic engineering, and more. This extensible model makes IS-IS a preferred protocol for modern networks. Dive deeper with our Mastering IS-IS series.

BGP route types are the language of VXLAN EVPN. They carry MAC, IP, and reachability info between VTEPs. Understanding them is key for building and troubleshooting EVPN fabrics, whether for multi-homing, L2, L3, or BUM traffic.

Domain Name System (DNS), the unsung hero.

Give your network automation a brain boost! 🧠 LangChain + Netmiko = an agent that understands natural language requests for device data.

In the world of computer networking, devices must resolve logical addresses to physical ones before they can communicate on a local segment. While we often think in terms of IP addresses (Layer 3), actual data transmission on Ethernet networks depends on MAC addresses (Layer 2). That’s where Address Resolution
