Yes, you can use what's called VM-ware. VM = Virtual Machine. Several operating systems now have VM server options where you can have many servers running on one physical server/machine.
Basically what it does is when computers get a distributed denial of service virus (ddos) they start sending packets of information to a server or a machine. The machine must then answer the packets using up processing space and if too much space is used by the requests, if there are enough machines and the server doesn't have a connection limit to prevent these attacks then it will prevent legitimate traffic from using the server or machine.

Using a home server can be more secure.You can secure your home server by putting a password on your server so no one can access your home server connection.
Some of the benefits of a server virtualization are; saving on manpower and hardware costs, stabilizing your servers, saving space in your data centers, and allows you to use your resources more productively.
The performance of a virtual machine is much faster compare to that of a physical machine. You can read more information at en.wikipedia.org/wiki/Virtual_machine
The -server flag for java in the jdk 1.3 selects the Java HotSpot Server Virtual Machine (as opposed to the default Client Virtual Machine). This VM is more optimized for long-running server-type programs, as opposed to short-running clients.
Server virtualization is the ability of a server to be masked from other users in a network. Sometimes, this involves the server being divided into several smaller, more private servers. The virtual machine model, the paravirtual machine model, and virtualization at the operating system layer are the three most popular ways to virtualize a server.
Using a caching only DNS server has an easier set up. Also, using this type of DNS server can transfer information more securely if proper security measures are in place.
The advantages of using a Linux dedicated server are access to more scripting languages and Linux is an open-source free software (costs less to make a Linux server).
VMware makes virtual server hardware and partitions a physical server into multiple virtual machines. You can read more at www.vmware.com › Products › Datacenter Products
Try to assign static IP addresses to servers?
Server rooms that attempt to be more energy efficient than standard server rooms, for example by using energy efficient components or using more natural cooling and less air conditioning.In addition a green server room might get its power from a "green" source like windmill or geothermal power.
Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments. The virtual environments are sometimes called virtual private servers, but they are also known as guests, instances, containers or emulations.
