I just did an MX lookup for sbcglobal.net, which yielded a bunch of hosts
with prodigy.net hostnames:
;; QUESTION SECTION:
;sbcglobal.net. IN MX
;; ANSWER SECTION:
sbcglobal.net. 4021 IN MX 10 sbcmx4.prodigy.net.
sbcglobal.net. 4021 IN MX 10 sbcmx5.prodigy.net.
sbcglobal.net. 4021 IN MX 10 sbcmx6.prodigy.net.
sbcglobal.net. 4021 IN MX 10 sbcmx1.prodigy.net.
sbcglobal.net. 4021 IN MX 10 sbcmx2.prodigy.net.
sbcglobal.net. 4021 IN MX 10 sbcmx3.prodigy.net.
And when I connected to one of them it seemed not to know it was an
sbcglobal.net MX:
