Why cant I do a lookup for IP Address for 10.151.107.17?

OrgAbuseRef: http://whois.arin.net/rest/poc/IANA-IP-ARIN|||10.x.y.z addresses are private, and are not to be routed to the internet. They may show up in email headers, from the sender's internal networks, but that is not the sender's ISP (public) IP address....





I use www.spamcop.net to parse and report spam mail. Sign up for free, and submit those headers, they will parse where it really comes from.|||Ip addresses beginning with 10.are in the private range and are internal addresses not usable outside their networks|||There are three IP address ranges that are reserved for private use. A private IP address is one that is used internal to your home, work, or school The addresses use are not ever broadcast to the internet. The internet address is the gateway to your home, work or school. This is the address the internet sees you as http://www.ipchicken.com/








The private IP address ranges are





10.0.0.0 鈥?10.255.255.255


172.16.0.0 鈥?172.31.255.255


192.168.0.0 鈥?192.168.255.255





In short, you can't look up that address because it is a private class A address. It is supposed to be internal to your network and not on the internet.
