Airtel is rolling out IPv6 on their wired broadband services

@nishantt6969 fall back to v4 is default behaviour. Chrome by default tries v6 and if that fails v4.

@Chip so is this normal?

@nishantt6969 yep that's default..I won't call it 'normal'. That's the way things are going to be even with the OS. Now for e.g. I have a v6 address and if I ping or trace route to a particular site it always picks the v6 address to ping on. If that's not available then v4. For e.g. when I ping google.com this is what I see:

C:\Users>ping google.com

If I want it to ping Google's v4 address only then i use the switch '-4' and then here's what I get:

C:\Users>ping -4 google.com

PS - notice the difference in ping times

Got it.

I got shifted to CG-NAT today morning and hence had to enable IPv6 on my Archer C1200 (which is in router mode, ONT is in bridge). The router page shows that an IPv6 connection is established with an IP address. However, IPv6 is failing when I test on websites. Any help please? TP Link router page

@blackpanther22 prefix delegation should be enabled.

Works now! Thanks @Lolita_Magnum

My router is getting ipv6 , but none of the devices are surfing over it. I have already enabled RA(SLAAC+DHCPV6), I am getting link local adresses with global also but not able to use IPV6.

 

[Lolita_Magnum]

SLAAC and DHCPv6, don't work together. What device are you using?

 

[JSMFPPJK]

I'm using richerlink one
