Final answer:
DNS servers provide IPv4 and IPv6 information along with directing email delivery by using various record types like 'A', 'AAAA', and 'MX'.
Step-by-step explanation:
The services capable of providing both IPv4 and IPv6 information as well as email service information are Domain Name System (DNS) servers. DNS translates domain names into IP addresses. This happens when you type a domain name, such as 'example.com', into your web browser, and your computer uses DNS to retrieve the website's IP address. Besides, DNS servers also contain records that direct email delivery to the correct mail servers. The primary record types for these functions are 'A' and 'AAAA' for IPv4 and IPv6 respectively, and 'MX' records for email services.
