Looking up hostname from URL

[guru]

I have a task of locating a server based off of URL

So what my thought process is would be to first find the IP address

ping url.com

Then if it is a Windows server, try and utilize

nbtstat -A ip.address or nbtstat -a computername

Tried

tracert url.com

then connected to last hop/switch

sh arp | incl ip.address
sh mac-address-table address mac.address

(may want to lookup mac address for vendor)

if it shows up on a trunk or multiple ports, see if its going to another switch

sh cdp nei

(look for the port that the sh mac-address-table address result included)

Also tried

nslookup ip.address

Also downloaded nmap and tried os detection but it couldn't identify the mac address

nmap -sVC -O -T4 url.com

Anyone have any other idea's for looking up information for a server in an intranet (internal LAN)

I use nmap also and have no idea on how else to do that
