IPv6 Support on Excitel Broadband

[JB701]

ISP Servers will need to be configured to enable IPV6CP (IPv6 PPPoE) . While I'm not completely sure where the backend routers are, afaik its located in LCO's NOC. These routers will all have to be properly configured for IPv6. Mikrotik routers don't even have IPv6 Package enabled by default (Excitel and most smaller ISPs use MikroTik hw).

 

[Realme]

Can't they mass configure from their main config server/router for e.g. ike BSNL did to auto-update all ONTs after BOTNET attack.?
^To this day I'm suspicious of my ONT as I disabled my TR and any other external-facing protocols

Does excitel give public IPv4 or it uses CGNAT

 

[JB701]

CGNAT, they don't even provide public IP on request (or even for payment).

afaik its located in LCO's NOC

Afaik LCO's NOC only has olts which have links from Excitel. Excitel provides OLTs to LCO's in case of Excitel Fiber, so that they can manage network themselves and i guess this is the main reason for LCO's who have fiber infrastructure already in place not to opt for Excitel Fiber as they have to get a new olt specially for Excitel only and deposit some security for the same. Routers may be located somewhere else at Excitel's NOC. You may be right about which routers they are using coz when aaaa queries were being dropped, the person along with which I did troubleshooting said to me its strange that aaaa packets are being dropped by excitel as practically aaaa queries should be answered on ip v4 also, seems like they have used some weird routers at their end.

So something strange is happening although internet is working. See nslookup output

C:\Users\opomiyulen>nslookup google.com
DNS request timed out.
    timeout was 2 seconds.
Server:  UnKnown
Address:  fe80::1

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out

Last time I checked nslookup output look liked this

C:\Users\opomiyulen>nslookup google.com
Server:  UnKnown
Address:  192.168.0.1

Non-authoritative answer:
Name:    google.com
Addresses:  2404:6800:4002:80d::200e
          172.217.167.206

If anyone can comment on this

 

[JB701]

Type in "ipconfig" and show the output.

@JB701 Here it is

[JB701]

fe80::1 is link local IPv6 address . I wonder why Windows is using that instead of 192.168.0.1.

Even I don't know, both IP v6 and v4 on lan are set to automatic dhcp. ok @JB701 I disabled and enabled the lan card and now its ok. I was checking this coz proble stopped resolving aaaa queries.
