I don't know if I am right but I always suspect that when the telephone
went digital in the 1980's, the differnce in the transmission of the
digital conversation and data converged into the same basic system.

Transmission only went digital between exchanges. The line from the
exchange to the phone is still analogue. It's converted to digital in
the exchange, sent to the target exchange and then converted back to
analogue and sent to the other parties phone. Otherwise everyone would
have had to replace their handsets with ones that contain D/A and A/D
converters.

I assumed this because of the a telephone number is the same number of
digits as a URL

192.168.01.01
919-333-3636

Is this assumption correct?

No, that assumption is not correct. What about an IP address of
1.2.3.4, it exists and someone will (most likely) be using it. If you
are adding leading zeroes your example must be 192.168.001.001 since
each value can be from 0 to 255.

The numbers are an IP address, a url is in letters (www.example.com).
