BSNL FTTH DNS PROBLEM

[varkey]

Yep, @abbyck had shared the resolvers with me earlier and I had the exact same observation. Anything which is not already cached takes a really long time to resolve like 2-3 seconds or more at times.

You guys are talking about DNS,HERE I am stuck with PPOE issues.Whole district facing issues with PPOE auth.
Why not use 218 series DNS?

@Kick933 DNS change was done by BSNL. I remember checking ping before it was changed and it was 8ms I think to 218 series DNS. I am not using BSNL DNS but sometimes I log in to the ONU just to check if something has changed and found it. Is your DNS still in the 218 series?

Anybody noticed BSNL changed the dns servers. It's 61.1.1.1 and 61.0.2.2 for me now and the pings to these are really slow, like minimum 20 ms and 50ms respectively.

that's done many months ago

@ps1193 not for everyone because mine changed just two days ago. Also, it's not as much about the change as it is about the pings. The servers are in the BSNL network and a little better ping is expected than connecting to an external DNS.

ohhh for me its changed many months ago but i am using ultradns

That's a technically correct assessment. On the contrary, I would urge you and everyone else to run your own recursive DNS server in your network. For most, running a recursive server seems to be a daunting task, I would suggest a relatively easier option - PiHole

Out of the lot who run a PiHole in their networks, most choose the default option i.e outsource the DNS to the quad DNS providers (1.1.1.1, 8.8.8.8, 9.9.9.9 etc). I would urge you to configure the PiHole such that it speaks directly to the root servers. Here is the link to the documentation on how this can be done in a PiHole.

So apart from the benefit of blocking ads, malware etc, this DNS server becomes closest to you for your devices. While it will not have a DNS cache as large as the cache of some of the quad DNS resolvers farms, turning on prefetch option in Unbound will make sure it popular items do not expire from the cache.

Another benefit of doing this - you get to see (and block) which(all?) of your devices(IoT - Internet of Trash) are calling back their motherships aka phoning home
