No need for grep if you are using gawk. You can turn case insensitivity on using IGNORECASE.
Code:
$ cat /etc/hosts
127.0.0.1       localhost
::1             localhost
....
192.168.0.115   admiralty
192.168.0.116   central
192.168.1.230   quarry
....
$ VAR1=Central
$ VAR2=$(gawk 'BEGIN {IGNORECASE=1} /'$VAR1'/ {print $1}' /etc/hosts)
$ echo $VAR2
192.168.0.116
