Cool Ideas Fibre ISP – Feedback Thread 6

Weekend usage on v6 and everything is running 100%. IPv6 is the preferred protocol but I think this is just how the internet is, if sites/servers don't support v6 it falls back to v4.

Got my DNS as well fully IPv6 I use Adguard home on a PI and then upstream DNS to a Technitium resolver in the DC so had to add IPv6 on my proxmox host and docker VM in DC.

I would stick with the CISP DNS servers but sometimes there is degradation on it so queries become slow. Sometimes it even goes offline

Thank you for the Valued Feedback, I will be sure to pass it along to the team.

Will ask them to check the DNS issue mentioned
EDIT:Do you have some examples perhaps on what kinds of issues you experience?

Which router are you using and how do you have your LAN configured ? I had some issues with some IPV4-only sites not loading

Confirmed with our engineer they have not picked up DNS issues as yet while testing V6.

Could possibly be the Adguard not liking V6 DNS?

Mikrotik hex - normal /24 ipv4 LAN, no VLANS or anything like that. then for v6 DHCP client attached to pppoe interface, I am only requesting the prefix on the DHCP client, then Neighbor Discovery aka router advertisement (RA) which is advertising the cool ideas prefix to all the LAN devices. There is no NAT on v6

I had some firewall rules that I made that was causing similar issues you speak of but I tried the rules from Web Squads thread and now everything works fine.

if you go to https://whatismyipaddress.com/ you should be getting both ipv4 and ipv6 addresses. Also, what DNS servers are you using?

Not in the case of this weekend just in general CISP DNS works flawlessly then randomly there will be degradation or it goes down, I switch to 1.1.1.1 or Google and DNS comes back.

I'm not sure if anyone else experiences that now and then when using CISP DNS.

I had a similar setup to you and the CISP prefix was only applied to 1 of my vlans. When i tried the various IPV6 test websites they all showed a valid IP address and in general browsing was fine except for those few sites and services that timed out or were very slow to load. On my pihole i have Quad9 and CLoudflare as the upstream v6 DNS

Reconfigured and getting the same issues as yesterday on my side:

ping test-ipv6.com

This is because funny enough test-ipv6.com doesn't have a AAAA record. Kind of funny that a site to test ipv6 only has an A record

Edit: if you ping mybroadband.co.za or google.com you should get a v6 reply. if you do ping -4 google.com you should get a v4 reply

Oh I see, thanks.
Have not seen any complains in this regard recently though. Does this happen often? And for how long?

So in the first instance the browser should still load the site (using v4)

The issue might be how my pihole is setup - let me dive into that rabbit hole and see if i can uncover anything

It should not matter what DNS server you use if you use ipv4 quad9 and cloudflare as your upstream they will be able to resolve ipv4 and ipv6 (A and AAAA records) and same goes if you use ipv6 DNS only.

Your LAN'S DHCP is issuing the PI'S IP > it forwards to quad9 & CF (9.9.9.9 & 1.1.1.1) quad9 & CF server will check for both A record and AAAA but as I mentioned earlier it seems AAAA is preferred over A

mybroadband.co.za actually only shows an A record on https://toolbox.googleapps.com/apps/dig

use https://toolbox.googleapps.com/apps/dig to check

yeah so looks like i have issues with sites that only have A records

Cant access github.com - no AAAA record
I can access reddit.com which has both

edit: on IPV6 that is
 
#COOL-20240606-1791067

Been having gaming related issues where connection test on Playstation Network fails or Nat type fails, when they both eventually work I struggle to connect to game servers specifically Warzone which will randomly work sometimes but FC24 doesn't work at all. I've attached traceroute to EA servers which shows they are being blocked for some reason, is this an issue that can be fixed?

Hi there, thanks for reaching out.

I had a quick scan through your ticket, and saw there had been quite a number of issues with the connection in the last month.

Can I ask, can you try setting up this Proxy (on the PS5) on your internet connection setup, and advise if there are any differences?

stuprx01.cisp.co.za - Port 3128
or
trcprx01.cisp.co.za - Port 3128


EDIT: Regarding your traces, If an IP times out or is not reachable, it doesn't necessarily mean it's blocked, it could be that ICMP is disabled. However one of your traces seems to time out on your 3rd hop, which is odd.

Just tried both proxies. Playstation Sign-in and Nat type still fail a few times which is what happens every time before they eventually work and this only happens with the Vumatel router

Warzone managed to sign in while FC24 strictly giving "servers unavailable" error

I did the traceroute multiple times and it gives identical results

Thanks, let me investigate a bit, and get some comparative test results.
