it has always bee 1 digit less than the assigned dynamic ip address given to me by my ISP. But now it is 1 digit higher
These are just made up IP address for illustrative purposes
example: Say my assigned IP address given to my ISP is 51.46.211.100. In the past the IPv4Default gateway would be 1 digit less 51.46.211.99
But now if my assigned IP address is 51.46.211.100, the IPv4 Default gateway is 51.46.211.101
