Alright, I did some basic testing with iproute2. I do not claim
to understand what I did but I ran the following:

$ ip -f dnet route add 1.661 dev em1
$ ip -f dnet route list
1.661 dev em1  scope link

$ ip -f dnet neigh add 6.662 dev em1
$ ip -f dnet neigh list
6.662 dev em1 lladdr aa:00:04:00:96:1a PERMANENT

$ ip -f dnet addr add 1.111 dev em1
$ ip -f dnet addr list
2: em1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
    dnet 1.111/16 scope global em1
