I dont know if this is enough for you, but whatever you want to do during
boot, providing you use standard init, can be done in /etc/init.d/rcS.
this is a line in my inittab:
si::sysinit:/etc/init.d/rcS
so edit this shell script, try putting read -p "enter address:" var; echo $var
wherever you like to.

you can of course run your own program from rcS. you can ask for the address
and perform your processing in separate script. it will be executed and the
script will continue asap your program ends (being it script or compiled
binary).

when in rome, do like romans do. look at the rcS script. follow it to the
point where you think you found best place to put your modifications to.
I'd bet you end up making symlink in /etc/rcS.d directory after reading
README there (and docs from sysv-rc or initscripts packages).
