bash script variables from file

How can I read the dns servers from /etc/resolv.conf so that I can use them as variables??

# get nameservers
for ((i=1;; i++)); do
read "d$i" || break;
done < /etc/resolv.conf

echo "$d2"  | awk '{ print $2 }')
echo "$d3"  | awk '{ print $2 }')

I need d2 and d3 turned into DNS1 and DNS2 respectively without the other text.

The files contents are;
