[SOLVED] sed: -e expression #1, char 23: unterminated `s' command

This code will get the new ip address of the wlan0 in each new network connections and then will update the whole line beginning with 192 in /etc/hosts:
Code: ip="$(ip addr ls wlan0 | grep '\<inet\>' | cut -d' ' -f6 | cut -d'/' -f1)"
echo $ip | sed -i 's/^192.*/'$ip' example.com exmaple.org/' hostsbut when i run this code git this error:
Code:sed: -e expression #1, char 23: unterminated `s' command
