Some theory about name resolution

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hello,

I'd like to understand better how the name resolution works.
In my company network, we don't use WINS. If I ping a workstation name
that is placed in my same VLAN, I can obtain its IP address without it
being registered in DNS. But when the workstation isn't in the same
VLAN, it isn't possibile and I'd like to understand better why.
Why does it ping in the first case? It's because of SMB protocol? And
how can I obtain the IP address of a ws. placed in a _known_ VLAN, but
not mine? Is there a technical way to do it?

Can you suggest me some reference to understand better the argument?

Thanks and regards,

misirion
