although this is not linux-l@ , here is a hint for those who keep
trying:

# /sbin/ifconfig eth1 240.1.2.3 netmask 255.255.255.0
SIOCSIFADDR: Invalid argument
SIOCSIFNETMASK: Cannot assign requested address
SIOCGIFADDR: Cannot assign requested address
SIOCSIFBROADCAST: Cannot assign requested address
# /sbin/ip add add  240.1.2.3/24 dev eth1
# /sbin/ip add show eth1
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:30:48:5d:0a:af brd ff:ff:ff:ff:ff:ff
    inet 240.1.2.3/24 scope global eth1

Now using this IP with the binaries that are of the same vintage as
ifconfig(), that's really a discussion for linux-l@ .
