* The Domain Name System (DNS) has several key roles, including:
* Storing the IP addresses associated with domain names.
* Translating human-readable domain names (aliases) into IP addresses that computers use to identify each other on the network.
* The other options:
* Creating IP addresses if it cannot find an alias is incorrect; DNS does not create IP addresses.
* Sending packets along a pathway that connects it to the Internet is the role of routers and not DNS.
* Therefore, storing the IP address and translating an IP alias to an actual IP address are the correct roles of DNS.
