Thanks for these. I have just checked them and they are:
184.108.40.206 & 220.127.116.11 which are level 3 DNS not your IP address or a PSN auth server.
Looping back to what velloony said it looks to be a DNS issue. Do you have a different DNS setup on your PS4 as that would sort of make sense even though DNS actually uses port 53 which the Geo-Filter services do not filter at all. There is likely some mismatching between the routers in your setup, please can you let me know your physical setup.
I don't know how that's possible unless the difference between my IP that displays on the Xr500 is different than either of those IDs. That is weird. Because the icon I select on the Xr500 shows the IP and it's mine. It's in the same general location as the icon on the R1. I assume they are the same. Weird.
Setup is simple. SB8200>Xr500 or R1> ps4 and 1 pc the ISP hands off to the router ISP of 18.104.22.168and 22.214.171.124. The ps4 is set to DHCP, the Xr500 or R1 are set to hand out default address ranges. This shows the ps4 network info currently as follows,
DNS 1: 192.168.1.1
In the R1 it will be .88 not .1
Another funny thing is the ico is in Chicago area yet my ISP is routed and located in Texas. Pinging or Tracert to 126.96.36.199 will always default route me to DFW peer vs. CHI.
DFW L3 DNS is a 16ms ping time.
