How to find a websites I.P. address the old fashioned way, through the command prompt. The best way to secure your network is to find it’s vulnerabilities before someone with less than honorable intentions does.
The first thing an attacker does when it acquires a victim is foot printing. They scour all of the public databases and find domains that belong to your company. They then map out your network to look for potential weaknesses. The first step they take in mapping out your network is acquiring an I.P. that belongs to each domain:
How to find a Web Sites I.P. Address:
1. Click Start
2.Click run, type in CMD, and hit enter.
3. When the Command Prompt screen opens type this:
Ping www.websitename.com
The results should look something like this:
pinging asa.asa.sdf.sdf.something.com [66.218.65.140] with 32 bytes of data
reply from 66.218.65.140: bytes=32 time=402ms ttl=55
reply from 66.218.65.140: bytes=32 time=601ms ttl=55
reply from 66.218.65.140: bytes=32 time=587ms ttl=55
Request timed out.
ping statistics for 66.218.65.140:
Packets: sent = 4, received = 3, Lost = 1, <25% Loss>,
Approximate round trip times in milli-seconds:
Minimum = 402ms, Maximum = 601ms, Average = 530ms
5. Obviously the four sets of numbers that are separated by periods (in this example 66.218.65.140) are the websites I.P. Address.
It’s very important to know this for security purposes because it is the first step an attacker will take to footprint your network, ultimately leading to the penetration, and possibly the takeover, of your entire network. The next step in mapping a network is port scanning (coming soon).
