Can I split/distribute my DNS between multiple ISPs ?
Posted on 2008-11-17
I have had issues with the ISP that hosts some of my domain names. Despite having resilient name servers for my domains, they managed to have a complete failure on all of them causing my domains to become unresolvable for a period.
I have some devices which allow me to enter multiple URLs, allowing me to add a URL hosted with the problem ISP as well as a second URL for a backup domain hosted with a different ISP that both point to the same destination IP address. However, I also have some devices that can only have a single URL specified.
My question is, am I able to register a domain name, and then assign authoritative name servers to it that are hosted by different ISPs ?
For example, could I register myisp.com with Network Solutions and then also go to another third party such as 123-Reg and also make their name servers authoritative for myisp.com in order to achieve ISP name server resilience ?
