But heres a thing – without DNScrypt i have no problem pinging the last one

but still have 10% packets lost (not a big deal its not 100)

is there any chance that i can make it work ? )

sorry i dont even really know what im talking about so please use simple words ))

tracert shows that it starting sending time out requests after it reach my provider i guess

C:UsersUser>tracert fl.com

Tracing route to fl.com [204.8.234.144]

I Hope theres a way to fix this thing <3

Help with redirection of DNS queries?

Hello all, I was wondering if I could get a bit of help here. I was on a team that implemented a solution some years ago to accomplish this but for the life of me, I can’t remember what we had done. I’m trying to do the same thing now and can’t fiure it out.

Say my client owns example.com. He has a DNS server that he wants to resolve queries for mail.example.com, but requests for www.example.com need to be resolved by his ISP’s DNS server.

Is there a type of record that I can configure on the ISP’s DNS server that says, “For www go to 1.2.3.4, for mail, ask 5.6.7.8 for the IP address” ? I know the first would be an A record but I’m lost on the second.

Appreciate any help. Thanks!

PowerDNS & TinyDNS

Hey gang,

So I have a PowerDNS server running on Ubuntu. It has the djbDNS backend enabled:

launch=tinydns,gmysql

gmysql-dnssec=yes

I have a script that pulls and compiles our customer zones from a SQL server into a data.cdb file.

PowerDNS can read this file just fine. My question is: If I want to enable DNSSEC for a domain in the data.cdb file, how do I go about doing this? Because it seems like I have to import that domain into the PowerDNS database and then run the “

pdnsutil secure-zone domain.com” command to enable DNSSEC.

Is there a way for me to enable DNSSEC on a domain that’s only on the data.cdb file?

Dynamically and scallably do views

I’m looking for a solution to creating a DNS server that allows for me to dyamically update views and handle a large number of statements. My goal is to create an ip specific DNS filter. I have looked at using bind-dlz with Berkeley DB, but I’m leery of it’s scale limitations. I have also looked at some interesting open source dns libraries like https://github.com/miekg/dns but it’s unclear on whether/how it supports views.

Client’s GoDaddy A Record yesterday mysteriously rolled back to previous IP address. This can’t happen, right?

We have documentation confirming the IP change (we implemented on GoDaddy DNS editor panel) a few months ago. Yesterday sometime the IP address reverted, taking the site down. GoDaddy’s explanation is the few-months-ago change *never happened.* . Anyone else ever been to this planet?
