@mary said in Common Ports - CompTIA Network+ N10-007 Prof Messer: @scottalanmiller makes sense. He did say outgoing to a DNS server. Thanks UDP itself has no connections, but that doesn't mean that a protocol running on top of it can't have its own connections. TCP makes connections for you, UDP requires you to do it yourself (if you want them.) So important to know that UDP itself does one thing, but can be used as a tool to make other things.

@DustinB3403 said in Weird TraceRoute Error: I got timed out at hop 8 along the trace route to 45.63.18.153 That's normal.
