Unicast (one-to-one), multicast (one-to-many), and anycast (one-to-nearest) — there is NO broadcast in IPv6. * The three address categories, with unicast's three sub-types and their prefixes. * IPv6 Address Types: Type Description Equivalent in IPv4 Unicast One-to-one; id...

A ULA (fc00::/7) is used for local addressing within or between a limited number of sites — like IPv4 RFC 1918 private addresses — and is never globally routed or translated to a GUA. Unique Local Addresses (ULA): Property Detail Range fc00::/7 (in practice fd00::/8, the h...

Connectionless (no connection set up first), best effort (delivery not guaranteed), and media independent (runs over any medium) — all chosen to keep IP overhead low. IP is designed with low overhead and has three characteristics: Characteristic Description Connectionless...

A default gateway is a router (or Layer 3 switch) on the LAN that serves as the door to other networks; it must have an IP in the LAN's range and be able to forward traffic off the LAN. Default Gateway (DGW): A router or Layer 3 switch that acts as the "door" to other networks. R...

A server provides information/services; a client requests them — and the same device can play either role depending on the exchange. Server and client are roles in a conversation, not fixed kinds of hardware. A computer is a server whenever it runs software that answers requests,...

Bandwidth is a medium's capacity to carry data — how many bits can move per second — measured in bps and scaled up as Kbps, Mbps, Gbps, and Tbps. Bandwidth is the capacity at which a medium can carry data - how many bits can flow from one place to another in a given amount of tim...

The cabling categories (Cat 3–7) are defined by TIA/EIA (ANSI/TIA-568) and ISO/IEC — not by IEEE. IEEE defines the Ethernet signalling standards (802.3) that run over those cables, which is a different thing. It is easy to mix up two different sets of standards bodies here, so ke...

Yellow jackets are single-mode fiber; orange (or aqua) jackets are multimode fiber. Fiber patch cords are color-coded for easy identification: Jacket Color Fiber Type Yellow Single-mode fiber (SMF) Orange or Aqua Multimode fiber (MMF) Common patch cord types: SC-SC M...

Unicast is one-to-one, multicast is one-to-a-group, broadcast is one-to-all — broadcast exists only in IPv4; IPv6 drops it and adds anycast instead. * The four delivery options compared from a single sender. * Delivery Option Description Unicast One-to-one communication -...
