So simple and useful

But I have a problem —-> when I want to write an IP address, I can not use a dot notation because don’t use a point (it’s look like this 176,16,0,0 instead of 172.16.0.0)

Could you solve this please 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼

It is showing numeric pad with , instead of . and as a result i cannot enter the address.
