Does :host "0.0.0.0" not work? Seems ok to me:

(setq proc (make-network-process
                 :name "foo"
                 :family 'ipv4
                 :service 6666
                 :host "0.0.0.0"
                 :server t))
                         
M-x list-processes

foo             --      listen  --                        --           Main         (network server on 0.0.0.0)
foo <127.0.0... --      open    foo <127.0.0.1:63650>     --           Main         (network connection to 127.0.0.1)
foo <172.26.... --      open    foo <172.26.128.66:63605> --           Main         (network connection to 172.26.128.66)
foo <172.26.... --      open    foo <172.26.148.3:63628>  --           Main         (network connection to 172.26.148.3)
