To change the resolution to an IP address, you need to modify the record type to A and enter the IP in the record value. If you need to resolve to an alias, you should change the type to CNAME. Type A corresponds to IPv4, type CNAME corresponds to alias records, and AAAA corresponds to IPv6 addresses.
