Networking on Linux
Sockets and routing are universal; Linux adds interface naming, iproute2, distro-specific network management, systemd-resolved, and netfilter. This overview focuses on the host stack on Debian and points to protocol detail elsewhere in the knowledgebase.
Docker networking
Docker connects containers with bridge networks, veth pairs, and drivers. This page covers compose-style networking; the Linux host stack—iproute2, nftables, and interface naming—is in the Linux networking chapter.
Ethernet and Switching
CSMA/CD (Carrier Sense Multiple Access with Collision Detection). In an old fashioned Bus structure all connected devices were listening and sending on the same wire one at a time. If a device…
IP Addressing
Classful Addressing was used mainly before 1995. Today Classless Addressing is used.
IP Routing
IP Routing is all about sending information from one IP address to another. That might sound like a straight forward thing to do, but it gets a bit complicated, because a destination IP address often…
Network segmentation
Network segmentation is a fundamental practice in modern network design aimed at enhancing performance, security, and manageability. By dividing a larger network into smaller, isolated segments,…
Network topology
There used to be Bus (every device on one wire) and Token Ring by IBM (a token goes around in a ring and visits every device), but today it is mostly a Star topology (many devices connected to a…
OSI Model
The OSI model groups network behavior into seven layers for teaching and troubleshooting. This page maps common protocols to those layers; Linux host configuration—interfaces, routing, and firewalls—lives in the Linux networking chapter.
