Recommend a good network scanner

[ShowdOWN]

Hello everyone, I was wondering if anyone was using a particular networking scanning software that they depend on. I need to be able to scan a network for available IPs and ports that may be open to check for vulnerabilities. Any assistance would be greatly appreciated.

thanks.
