in the examples given above everything between the // and the @ sign is fake and added in and you will be directed to 10.19.32.4 what ever that resolves to (to lazy to dns lookup) if you ever want to know where a link goes go to dnsstuff.com and do a dns lookup or traceroute if its like
http://ebay.ca%40192.168.0.1 then your not going to ebay your going to 192.168.0.1.
Most browsers dont allow this anymore however some do so just be careful, if you want more info you can look up dotless IP and D-words and the %40 is the hex value for the @ sign so watch for that too.
If you ever not sure just traceroute or ns lookup or simply ping the url and it will resolve back to an IP address this is all part of the DNS lookup on the internet.
