My IP address tends to be blacklisted because it is DHCP assigned. So I

have current info on Comcast.net?
This list below is what I am using. Where I have "new" is from this year.
I just found one of them a few minutes ago! Seems like a never ending
battle.
"ip4:63.240.76.26 " ; old
"ip4:63.240.77.83 " ; new
"ip4:204.127.192.0/25 " ; new

Does anyone know if comcast.net will publish a spf record anytime soon?
Maybe someone could recommend a better method of listing Comcast.net
outbound servers? smtp.comcast.net does not cover all of them, maybe less
than half. And from outside of comcast's network the DNS info could be
different. I can't tell from inside!
Guy, write a script to check for a records. From my notes from when I used
the Comcast MTAs (and it looks the same from your mail), Comcast mail servers
follow the following patterns:
EIther
sccrmhc12.comcast.net
or
rwcrmhc13.comcast.net
With only the numbers varying:
$ dig a rwcrmhc13.comcast.net +short
216.148.227.153
204.127.192.83
$ dig a sccrmhc13.comcast.net +short
204.127.200.83
63.240.77.83
I'd suggest writing a script to pull out the IP addresses for you.
