you may want to seriously reread the previous sender's message.  the point
is that in the modern post-2182 world, many of the client's nameservers are
vastly net.distant from the client.

    psg.com nameserver = DNS.LIBRARY.UCLA.EDU
    psg.com nameserver = RAIN.PSG.COM
    psg.com nameserver = ARIZONA.EDU

it is best common practice.
