Comcast routing my busniess static IP a bad path compair resident DHCP IPs path.
I try so many times to talk to tech support on this, they just don't understand how BGP and peering works....
I am trying to access a colo server at Serverna.net and I notice my business static IP are getting a constant ~10% packet loss up to 100ms latency. If I use my neighbor's Comcast that is a resident DHCP 0% packet loss with at a steady 20ms latency to the same colo server. Seems kinda on unfair to have Comcast send its business customer to a worse path then a lower paying customer.
from the server to my Comcast business IP:
[root@server ~]# ping 173.164.225.XX -A -c 100 -q
PING 173.164.225.XX (173.164.225.XX) 56(84) bytes of data.
--- 173.164.225.XX ping statistics ---
100 packets transmitted, 92 received, 8% packet loss, time 5865ms
rtt min/avg/max/mdev = 43.549/57.743/87.025/9.627 ms, pipe 2, ipg/ewma 59.249/62.106 ms
[root@server ~]#
and here is from the server to a comcast DHCP IP:
[root@server ~]# ping 73.170.59.XX -A -c 100 -q
PING 73.170.59.XX (73.170.59.XX) 56(84) bytes of data.
--- 73.170.59.XX ping statistics ---
100 packets transmitted, 100 received, 0% packet loss, time 3592ms

[root@server ~]#
Here is the path that Comcast is advertising my static IP to:

It would be nice if comcast would not be doing this to me.

route change was just done, latency and packetloss went away and both networks are now taking the same path.
