What's keeping ftp.sc.edu from an A

  1. ftp.sc.edu is an alias of sc.edu, which has no IPv6
    ftp.sc.edu is a CNAME, so it can't also have its own AAAA record. Ask whoever runs sc.edu to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6

What this means

Visitors on IPv6-only networks (many mobile carriers) can still reach it, but only through a translator their carrier runs (NAT64). The site itself has no IPv6 address — and you can't make one up from the IPv4. Why some hosts don't offer it
