According to the Image:-

“IP Address: Unique Device (host) Address.”
What is a host?

“Default Gateway: IP Address of the Router on the Same Physical Segment”
What is a Physical Segment?

Best answer:

Answer by Tim the Tech
A host is a device that is using the IP address, like your PC or laptop.

Same Physical Segment in a nutshell means that it is in the same IP range as your host, so if your IP address is 192.168.10.100 with a subnet mask of 255.255.255.0 then in order to be in the same physical segment your router would need to have an address of 192.168.10.X.
This could get really in depth if we start explaining subnets etc., but in short form when a subnet mask is 255.255.255.0 it means that any device that wants to communicate with it must have an IP address that matches the first 3 sets of numbers. A subnet mask of 255.255.0.0 means that it only has to match the first 2 sets of numbers (in this example 192.168.X.X) and 255.0.0.0 only needs to be in the 192.X.X.X range.

Question by championForever: Tomcat 4.1 : Set default virtual host. Simple question?
I am using Tomcat 4.1. My web application is located at …/webapps/myApp

So this is my setting at server.xml

unpackWARs="true" autoDeploy="true">

To configure the tomcat for your web application you have to conigure the Context.Not virtual host.

The Virutal host should be like this

unpackWARs="true" autoDeploy="true">

For configuring your application context.scroll down the file till you find
below that make an entry for your application like this

reloadable="true" crossContext="true"/>

this will solve your problem.
