Thanx, Kevin, for the info. Apparently when I bought the license to
my domain name & calss-C block in 1995 or 6, I got a "portable"
block. I have changed ISP's twice since then & an additional change
of registrar. No-one has ever mentioned any charge for keeping
my domain name & its associated address block. The fee went up
from $25/yr to $35/yr about a year ago. I guess I got lucky jumping
on the bandwagon early enough. Even so, I would feel like a robber
baron charging more than, say, $1 / yr per address, a 6140% markup
(ignoring the wasted @'s if I followed the subnetting RFC
!! Apologies to the list: this response was delayed for several hours
because my ISP is having problems.
