What is IP: 0.0.0.0

In the context of a route entry, it usually means the default route. In the context of servers, 0.0.0.0 means all IPv4 addresses on the local machine. If a host has two IP addresses, 192.168.1.1 and 10.1.2.1, and a server running on the host listens on 0.0.0.0, it will be reachable at both of those IPs.

    IP address 0.0.0.0 has several special meanings like it is a non-routable meta-address used to designate an invalid, unknown, or non-applicable target. In the context of servers, 0.0.0.0 means "all IPv4 addresses on the local machine".

    Also, Computer and other devices normally show 0.0.0.0 when they are not connected to any TCP/IP network.

    Track geo-location of any ip address with IP Location Finder tool.

HowTo: Enable extended logging for exim

When troubleshooting mail or attempting to discover the source of spam originating from your server, it is often useful to enable extended Exim logging. You can enable extended logging for exim though your shell prompt as well as through WHM interface. I am giving the steps for both ways one by one: 1. Through shell prompt: 1.
