<br>
<br>I've had AT&T Gigapower fiber (1G symmetric) for a few years now, with a
<br>/29 static IPv4 address. I feel like the Comcast networking group "gets
<br>it" better than AT&T does. Even though I've got 1Gb, and can get 900+
<br>Mbps speedtest, I really only see about 250Mbps for real usage (fast.com).
<br> I can't really compare this to Comcast, as I only had a 100M/12M
<br>(asymmetric) connection from them.
<br>
<br>When I first got it, AT&T was using 6rd, and I could only get like 1Mbps
<br>via v6. So I turned it off. I have v6 connectivity through and HE tunnel
<br>and also from a co-op I belong to up in Boston (via a GRE tunnel).
<br>
<br>More recently I learned AT&T swapped over to DHCPv6-PD, and I was able to
<br>set it up locally. AT&T now gives a /60 via -PD. So I set it up on my
<br>network (for a while). I found the v6 performance was about half my v4
<br>performance (although finding a real v6 speedtest that isn't speedtest.net
<br>is hard), but worse, facetime stopped working while the v6 network was up.
<br> It's possible this was due to a firewall configuration issue, but I
<br>didn't want to spend too much time on it so I turned it off due to WAF.
<br>
<br>One day I will look again.
