What is 172.16.0.1?
172.16.0.1 is a private IP address in the 172.16.0.0/12 range (172.16.x.x through 172.31.x.x) defined by RFC 1918. This range is used in enterprise and corporate networks where the 10.x.x.x and 192.168.x.x ranges are already in use. Docker also uses the 172.17.0.0/16 range by default for container networking.
