We see
       del addr/prefixlen
              Remove an IPv6 address from an interface.
However, no mention is made of how to remove an IPv4 address.
Trial and error found a way:

# ifconfig eth0

ip addr del 192.168.44.1/24 dev eth0

(It really needs iproute2.)

That's nice however I'm talking about the ifconfig man page, not the ip
man page.

Indeed some mention of the corresponding IPv4 pair for
       add addr/prefixlen
              Add an IPv6 address to an interface.

       del addr/prefixlen
              Remove an IPv6 address from an interface.

should be made, even "if it is obvious" somewhere.
