You say "... should be resolving to IP address 152.79.198.9." However,
according to dig:

    ;; QUESTION SECTION:
    ;unexdlc.ucdavis.edu.           IN      A

    ;; ANSWER SECTION:
    unexdlc.ucdavis.edu.    7200    IN      CNAME   extensiondlc.net.
    extensiondlc.net.       86364   IN      A       204.11.233.24

so, in fact it isn't. It looks like the UCD nameservers are
misconfigured.
