Frequently Asked Questions
What is DNS?
DNS (Domain Name System) is often called the phonebook of the Internet. It translates human-readable domain names (like ratoolz.com) to machine-readable IP addresses so browsers can load Internet resources.
Why are my recent DNS changes not showing up?
DNS changes can take anywhere from a few minutes to 48 hours to propagate globally. This is due to caching by local ISPs and routers. The "TTL" (Time To Live) value indicates how long a record should be cached.
