hostname

utility to set/show the host name or domain name

This package provides commands which can be used to display the system's DNS name, and to display or set its hostname or NIS domain name.

net-tools

NET-3 networking toolkit

This package includes the important tools for controlling the network subsystem of the Linux kernel. This includes arp, ifconfig, netstat, rarp, nameif and route. Additionally, this package contains utilities relating to particular network hardware types (plipconfig, slattach, mii-tool) and advanced aspects of IP configuration (iptunnel, ipmaddr). In the upstream package 'hostname' and friends are included. Those are not installed by this package, since there is a special "hostname*.deb".
