DNS is a very important part of your website. It ticks away in the background, busily directing visitors to the correct server. When you type in a web address into your browser, DNS changes that into an IP address. e.g. www.netweaver.uk to 184.108.40.206. This allows the browser to find and display your website.
This has to happen very quickly, otherwise, the website will take longer to load and your visitors may lose interest and go elsewhere. It also has to be extremely reliable. Domain registries mandate that you need to have 2 DNS servers for your domain. However, it’s quite possible to have both of those on the same actual server – and this is quite commonplace. It is a bad way to do DNS.
There are a lot of documents published, referred to as RFC (request for comment) which offer advice on best practice for internet services. RFC 2182 gives information on how to ensure a DNS service is diverse and resilient.
In short, RFC 2182 recommends at least 3 DNS servers, running on different networks and in different physical locations.
We operate, funnily enough, 4 DNS servers – all in different locations, on different networks and even on different domains to ensure there will never be a DNS outage.
|York (UK) – ns1.netweaver.net||London (UK) – ns2.netweaver.uk|
|Ballasalla (Isle of Man) – ns3.netweaver.im||Paris (France) – ns4.netweaver.eu|
We use 4 different domains so that a problem with one of our domains wouldn’t cause an issue with DNS. Such diverse DNS helps us ensure 100% uptime on our DNS as well as extremely fast response times.
Can I use these on my account?
If you use our DNS, then you already are. However, you can make use of all 4 locations (instead of the previous 2) by following the instructions below.
Any new accounts or domains are automatically configured to make use of these DNS servers. If you have your domain registered with us, you can switch over via https://my.netweaver.uk. Once logged in:
- Click the ‘Domains’ box
- Click the icon
- Click ‘Nameservers’ on the left
- Select the ‘Use default nameservers’ option
- Click ‘Change Nameservers’
That’s it – you’re now fully connected to our diverse DNS system.
If your domain is registered elsewhere, you can use your domain providers control panel to change your DNS servers to:
