domain name resolvers
Also called resolvers, domain name resolvers are the names given to computers, commonly located with Internet Service Providers (ISPs) or institutional networks that are used to respond to a user request to resolve a domain name. These computers translate a domain name into an IP address. Also called DNS resolvers.
