I did not see the "info" tag, thanks. Here is what I have for
my "A" recordes in thought.org's external [and internal] filees.
Note that plsto and ns1 are different computers. plato is my
thought.org.e.hosts:19:ethic A 18.104.22.168
thought.org.e.hosts:20:plato A 22.214.171.124
thought.org.e.hosts:21:ns1 A 126.96.36.199
thought.org.i.hosts:14:ethic A 10.47.0.230
thought.org.i.hosts:15:plato A 10.47.0.1
thought.org.i.hosts:16:tao A 10.47.0.250
thought.org.i.hosts:18:zen A 10.47.0.190
FWIW, ethic *is* ns1. LAst time someone criticized having
three IP's with the same quad decimal.
(A couple years ago I was sown for several days and my wife had
to talk with some tech [from Qwest]. He was either in Mumbai or
Manilla and had her erase a bunch of lines from my
"modem"/router. I don't think that has any effect here, tho I
may be wrong.)

I saw that and chaanged it, allowing transfers a day or two ago.
Where do I look in /var/log/ to see if these actually happened?
It may be that everydns.net got tired of requests and I need to

Thankee much. I'll grep around for xfer in /var/log/* and
hopefully see something from I recognize.)
