I have a domain registered with Fasthosts (animesoc.co.uk). I've recently hosted a forum on an external server (with IP address 22.214.171.124), and pointed the subdomain http://forums.animesoc.co.uk/ to this by adding the corresponding A record.
The issue is that when I try accessing 'forums.animesoc.co.uk' through a browser (tried from multiple different computers), it keeps switching between the website I actually want and a blank domain parking page with advertisements. It resolves to the IP address I mentioned above for about 1 hour or so, then starts giving me the domain parking page, switches back again to the forums and so on and so forth.
On using a DNS resolver service like http://tracert.com/resolver to check what the 'forums' subdomain resolves to, I get the following result
Resolution of forums.animesoc.co.uk resulted in the following IPv4 addresses:
I'm not sure why it's resolving to two IP addresses when I have only the single A record for forums (pointing to 126.96.36.199). Furthermore, I do not have the IP '188.8.131.52' present anywhere in my DNS settings so I'm not sure where that's come from.
I assume that the switching between the actual website and the domain parking page is occurring due to the subdomain resolving to this extra '184.108.40.206' IP address as well. How can I make the subdomain 'forums.animesoc.co.uk' resolve to just one single IP address (220.127.116.11)?
