I believe it will help you to know that dig has a "short" mode:
Code:
dig +short txt google.com

produces:
Code:
"v=spf1 include:_netblocks.google.com ~all"

I don't know what your sed command really does, but you can combine it with the cut-quotes command:
Code:
sed 's/"//g; s/ip4://g;'

I'm not sure what the complaint about "recursion" is: If you encounter an "include", you need to "follow it", recursively:
Code:
get_dns_spf1() { 
   dig +short txt "$1" | 
   tr ' ' '\n' |
   while read entry; do 
      case "$entry" in 
         ip4:*)  echo ${entry#*:} ;; 
         include:*) get_dns_spf1 ${entry#*:} ;;
      esac
   done |
   sort -u
   ;
}

This outputs a list. To get the output of the list in an array, just do:
Code:
ips=(`get_dns_spf1 some.site.com`)

Now you can just
Code:
echo ${ips[*]}
