什么是端口 42?
Originally assigned as the Host Name Server protocol on ARPANET, port 42 was later repurposed by Microsoft for Windows Internet Name Service (WINS), which resolves NetBIOS names to IP addresses. WINS is a legacy name resolution system superseded by DNS and Active Directory. Exposure of WINS on the internet poses reconnaissance and potential exploitation risks.
