IPv6 trials?

I was connecting to the Internet via a D-Link DWP-157 dongle and, to my surprise, saw that BSNL had given me an IPv6 DNS address too.

ModemManager[11712]: <debug> [1438849920.459234] [mm-bearer-mbim.c:258] ip_configuration_query_ready(): IPv6 configuration available: 'dns'
ModemManager[11712]: <debug> [1438849920.459245] [mm-bearer-mbim.c:285] ip_configuration_query_ready():  DNS addresses (1)
ModemManager[11712]: <debug> [1438849920.459263] [mm-bearer-mbim.c:290] ip_configuration_query_ready():  DNS [0]: '2001:4490:e000::1270'
ModemManager[11712]: <debug> [1438849920.459325] [mm-port.c:95] mm_port_set_connected(): (wwan0): port now connected

This IPv6 address is allocated to BSNL, and it is actually a DNS server. I tried connecting to it from a VPS, and it refused all queries. This is not bad behaviour as it only means that it is not an open DNS resolver.

I disconnected and tried connecting again after some time but did not get any IPv6 configuration.

So I guess BSNL is testing IPv6 deployment in some areas. This is great news; hopefully BSNL will provide native IPv6 connectivity to both ADSL and 3G users real soon now. It is sad that Airtel did not use IPv6 for its 4G services.

There's another IPv6 DNS server for 3G: 2001:4860:4860::8844.

Oh, that IP is of Google Public DNS, not BSNL's own server. On 3G IPv4 connections, BSNL uses 8.8.8.8 as the primary DNS server; in IPv6, it is using Google Public DNS as the secondary DNS server.
