AT&T Fiber 1Gig Service = multiple Public IPs
Having a number of service issues with my Gig service so trying to shoot down a few ideas. Any one know why AT&T started using two different IPs based on protocol. 45.x.x.x WAN address for HTTP(S) and 104.x.x.x and 198.x.x.x for other protocols (e.g. SSH)? I understand for traffic mgmt, but it appears it might be impacting a number of inconsistent speed issues (wired and wireless). Also, certain tools like OpenDNS don't work with these dual IPs.
Anyone in AT&T Traffic Mgmt / NOC explain why? (vs. theories)

What do you mean by "using two different IPs"? Using for what? Your gateway's external IP? The next hop in the route after your Gateway? Can you explain further?

On the WAN side of the BHR (Pace). I connect to a website and it says I have source IP address 45.x.x.x, I connect to a SSH server and it says I have a Source IP address 104.x.x.x (I am not using a proxy or Tor or any special / weird software setup). OpenDNS can't even handle it for its filtering.

Have you tried this with multiple SSH hosts to confirm that there's not just some mis-configuration at that SSH host? And/or web sites (I'm assuming you're using something like whatismyip.com)?
Also, can you provide at least two octets of these IPs? 104 and 45 are pretty fragmented as to where they're assigned.
