Is Nmap useful for outside scan or only for internal scanning?
What tool should I use to perform outside network scanning to know which host is alive ports and services?

Greetings, @ronnie-finkel
Nmap can be used for both private and public network scanning, but isn't the only tool that can do that.
Masscan is another popular port/host scanning tool.
I hope that helps.

for instance I have a client that his company called abc.com and if I want to scan over the internet a specific IPs that belong to a company abc.com thier internal network is it possible .
sinerio that could be happaned that my client want to to know if from outside some can attack.
I know that this case it's half work because mosts of the attacks occure from inside for several reason eployee that got fired or his boss made him anger and he want a revange.
but I'm looking from the outside because this case most of the people think that the probability to occurs is the highest one.
finally the job has to be done and I want to having a deal with more companies.
For now I just building myself to work as self empoyed in this field.
