Hostname
A hostname is a human-readable name that identifies a computer, device, service, or other host on a network and can be resolved to an address.
Acing the CCNA Exam: Volume 2 Advanced Networking and Security
A hostname is an identifier for a specific device on a network, expressed as either a simple name or a fully qualified domain name.
- How it is used
- Uses hostnames to identify devices and support DNS-based communication instead of requiring users to enter IP addresses.
- How deep it goes
- Defines simple names, FQDNs, and PQDNs, then demonstrates Cisco IOS configuration and verification without exploring DNS internals.
- Examples
- Uses www, srv1.example.com, Cisco IOS host mappings, show hosts output, and ping pc2 to demonstrate hostname resolution.
- What you can do after
- Operate/configure Cisco IOS hostname resolution with ip domain name, ip host, show hosts, and ping.

A hostname is a human-readable network name that identifies a host or service for network communication.
- How it is used
- Routes container-to-container requests through Docker Compose service names instead of host-exposed addresses.
- How deep it goes
- Demonstrates hostname resolution with Compose services and curl, but defers broader database connection setup and drivers.
- Examples
- Uses NGINX and Redis services, curl commands, Compose files, and an interactive shell inside the web container.
- What you can do after
- Operate Docker Compose services by testing internal connectivity with curl and addressing dependencies by their service names.
