An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to each device that uses the Internet Protocol (IP) for communication.
An IP address is a 32-bit number; written as four numbers with dots or periods between the four numbers. Example: 192.168.123.132
An IP address serves two main functions: host or network interface identification and location addressing. Accordingly, the first part of the P address is used as a network address, and the last part as a host address.
Stuff you wanna know:
- Kubernetes IP addresses exist at the
Podscope – containers within aPodshare their network namespaces – including their IP address and MAC address. - Pods on a node can communicate with all pods on all nodes without NAT.
- Agents on a node (e.g. System daemons, Kubelet) can communicate with all pods on that node.
