You csn not do this in bash directly. bash does not have builtin support for resolving ip addresses. You do need a proramm that will do it.

You could use dig. E.g. if you have your names in a file hostnamelist you could use the following script:

while read x; do echo  "$x "`dig +short $x A`; done < hostnamelist
