libdumbnet-dev 1.12-9build1 (amd64 binary) in ubuntu focal

 libdumbnet provides a simplified, portable interface to several low-level
 networking routines, including
   * network address manipulation
   * kernel arp(4) cache and route(4) table lookup and manipulation
   * network firewalling (Ip filter, ipfw, ipchains, pdf, ...)
   * network interface lookup and manipulation
   * raw IP packet and Ethernet frame transmission
 .
 libdumbnet is known as libdnet in other distributions, but was renamed
 in Debian in favour of the older DECnet library 'libdnet'.
 .
 This package contains the static library and the C header files.
