With virtualization trending among organizations, almost all of the IT departments are adopting virtual devices and applications in their infrastructure. According to Gartner, the worldwide server virtualization market is reaching its peak. The firm reported that growth is driven by maintenance and not new licenses. Despite the overall market increase, new software licenses have declined for the first time since this market became a mainstream more than a decade ago. Growth is now being driven by maintenance revenue, which indicates a rapidly maturing software market segment.

Today, as more than 94 percent of companies around the globe are deploying virtualization solutions, network administration has become more complicated with new challenges popping up every day. To tackle these challenges, there is a need of superior network infrastructure services that can deal with the changing network environment with simplicity and dynamicity. Meanwhile, Dynamic Host Configuration Protocol (DHCP), IP Address Management, and Domain Name Service (DNS) that are capable enough for managing the versatile virtual machines have become an important aspect in infrastructure virtualization.

For leveraging the power of modern virtualization, organizations need a robust and simple solution and latest implementations of DHCP, DNS as well as the IP address manager. The Dynamic Host Configuration Protocol (DHCP) offers the Internet Protocol addresses, gateway details as well as the subnet mask for a device based on the devices Media Access Control (MAC) address-that is created dynamically upon the virtual devices initial startup.

As the traditional hardware based computing devices and appliances are incapable to handle the modern IT requirements, organizations are leveraging the latest DNS and IP virtualization techniques to streamline the outdated hardware devices. Today’s innovative applications in the virtual environments are proven to be faster, reliable and cost-effective as well.  

The adoption of IP address Management solutions have made network administration simpler and easier. These applications are capable of automatically tracking both the physical and virtual addresses of devices including automatic assignment and release, thus eliminating manual entry of data in spreadsheets. DHCP is the protocol that assigns any physical device with an IP, subnet, and gateway according to the physical address or the MAC address.  Whereas, in a virtual infrastructure the physical  or the MAC address of a virtual machine will be assigned dynamically during the startup of the device, reducing the chances of creating a unique MAC address. To tackle this issue, the DHCP has to be completely automated, followed by allowing the same services dynamically for assigning the virtual machine physical addresses.

While the previous DNS systems comprised of simple mapping of names with addresses, the virtualization era has transformed it completely. Today with virtualization, the DNS is efficiently used as a service agent that can map the physical and virtual addresses dynamically. DNS services then acts as a switchboard for supporting the virtualized infrastructure, transforming it into a dynamic DNS architecture.
