Docker container can't access internet with specific ip

I'm trying to assign ip address to docker container. I already tried https://stackoverflow.com/a/35359185/10956041. also tried create network with docker network create --driver=bridge --subnet=193.111.77.0/24 --gateway=193.111.77.1 br0 and assign ip to container with docker run --net br0 --ip 193.111.77.183 -it ubuntu bash but again can't access to internet.
