Does all that stuff I wrote yesterday make sense?
Anyway, regarding periodically changing WAN IP addresses, I've sent a contact us
question to my ISP regarding basically the same thing as what you found online.
Their online FAQ suggests that they only provide dynamic IP addresses for residential customers,
which may change periodically.
Ok I thought, so I asked if they could send me some sort of notification (email?) if/when they
"periodically" change my IP address and let me know what it is. Or, failing that, could I call in
(if I can't access the router/IP remotely) and after being properly identified (they have all kinds
of security Q&A stuff on file for me), provide me with my "new" IP address that the router sees?
I told them I have some applications which require a known IP address to function properly.
I'll see what they say. Here's hoping they'll try to satisfy the customer.
Failing this, I'll pursue the free DLink hostname/domain/website thing with them, as the doc on their
free DDNS site suggests they can handle dynamic IP addresses and can update your space accordingly
when it changes. I'd just rather not have to rely on someone else to provide me with access, particularly
when it's free.
We know how reliable that can be???
