If you constantly use your laptop or PC between several different internet connections, then you’re probably tired of having to constantly configure them. Entering proxies, static IP addresses and other LAN configuration data can be really annoying if you have to switch quickly or regularly. NetSetMan takes the pain out of this by allowing you to rapidly change between pre-configured network settings.

The free version of this program (for non-commercial use only) allows you to create 6 profiles – more than enough for most users - including IP address settings, Subnet Masks, Default Gateways and DNS servers. These settings are then saved as tabs which you can flick between and activate according to the connection you are using. Other settings you can configure are the Computer Name, WINS Server, Default Printer and Run Scripts.

If you've never dealt with DNS then it can be pretty daunting. DNS stands for Domain Name System which is basically a network of numerical addresses that provides the framework for the internet to work. If you want to set up a server or redirect your website, then you'll need to know a little bit about DNS administration. Here are 5 top tools to take the pain out of this process:

• Simple DNS Plus - Helps you configure it as a primary or secondary DNS server

• NetSetMan - Helps you configure several DNS profiles if you regularly change networks

• DeEnesse DNS Server Suite - A beginners guide to setting-up a DNS server

• DNS4ME - Simple DNS server for e-mail, web and FTP for intermediate users
