Guile has `gethostbyname':

guile> (gethostbyname "localhost")
#("tortoise" ("localhost") 2 4 (2130706433))

The returned value is a vector from which the list of numerical
addresses can be retrieved with `hostent:addr-list'.

guile> (hostent:addr-list (gethostbyname "localhost"))
(2130706433)

The car of this list is the first numerical address.

guile> (inet-ntoa (car (hostent:addr-list (gethostbyname "localhost"))))
"127.0.0.1"

HTH.

Requiring 1.3.4 would be safest, that is what Debian 2.2 comes with.
Don't know about SuSE or RedHat.  I don't know if that is doable, as a
lot has changed since then.

Maybe 1.4 is a safe assumption also.  D'loading and installing 1.4
should not be more trouble for ppl than d'loading Sizzle.
