[TriLUG] About time-warner broadband

[David Burton]

I don't know that T-W blocks any ports, but most big mailservers block SMTP
(port 25) from mailservers on dynamic IPs, by checking reverse DNS, or by
checking sorbs and/or spamhaus:
http://whatismyipaddress.com/blacklist/spamhaus

To check your IP, see:
http://whatismyipaddress.com/blacklist-check
and http://remote.12dt.com/

My Time-Warner residential IP (which is "dynamic" but hasn't actually
changed in many months) is blacklisted on:

dnsbl.sorbs.net
dul.dnsbl.sorbs.net
pbl.spamhaus.org
zen.spamhaus.org
dyn.shlink.org

How does your T-W Business Class compare w/r/ to the block-lists?  (And do
you have the static IP option?)

BTW, has anyone talked T-W into selling them a static IP for Residential
Class service?

That's almost certainly your best bet, if AT&T U-Verse isn't available.
 Not satellite, that's for sure!

However, you can probably get AT&T DSL (current promotional rate $15/mo)
even *without* land-line voice service.  Once upon a time they wouldn't
sell you DSL w/o a voice line, but that changed some years ago.
