Description: DHCPv4 and DHCPv6 dual-stack client (binaries and exit hooks)
 dhcpcd provides seamless IPv4 and IPv6 auto-configuration:
  * DHCPv4 client
  * DHCPv6 client with Prefix Delegation (PD) support
  * IPv4LL support (ZeroConf)
  * IPv6RS support (SLAAC)
  * ARP address conflict resolution
  * ARP ping profiles
  * Wireless SSID profiles
 .
 This package provides the binaries, exit hooks and manual pages.
 .
 It offers a dual-stack substitute for ISC DHCP Client (dhclient) on systems
 where interfaces are configured by ifupdown via </etc/network/interfaces>
 using the DHCP method.
 .
 The init.d script and systemd service required for systems without ifupdown
 are packaged separately as dhcpcd.
 .
 Since Debian 12 (Bookworm), dhcpcd uses Predictable Network Interface Names
 on Linux ports. See NEWS.Debian for more details.
