I want to build a solution that uses powerDNS/Blocky (or any other DNS) to create a network-wide ad and domain blocking service for multiple customers (tenants). ​ Here’s the breakdown: ​ Multi-tenancy: I need to support managing separate block lists for each customer. Ideally, a single powerDNS instance would handle everything. Customer assignment: I’m unsure … Read More “DNS Service to create a network-wide ad and domain blocking service for multiple customers (tenants) : Need suggestions” »

I’ve never experienced this and need urgent help as GD and SS aren’t helping me at all. ​ I connected a GoDaddy domain (which was previously connected to a WordPress site) to a Squarespace site last Friday. But any DNS checker show 50% of servers still have a red X beside and no more servers … Read More “URGENT About to yank my hair out over GoDaddy domain trying to connect to Squarespace website” »

Hello, Checking my PiHole today I noticed a couple of strange DNS requests going to the following domains: x016b6579303530393230323300000000000000000000000000000000000000.x00000000000000000000ef144d87502845f7f3eb7f17f13f7d3c1c77e02388.x1d6a479a363476f1f4847efea9baaf6bb533124bc895b334df8eb3542e8cdb.x69 and x016b6579303530393230323300000000000000000000000000000000000000.x00000000000000000000a9a7d91008fb8ec52250bccfdae9b294e9d6179f56.xe1d8415f8d20737876296d41b1f3b643a663db464d5112a79038206d3cd17c.xbf Both requests are A-record requests and show as coming from my OPENWRT router BUT that does not mean the requests actually came from that device, as any DNS requests that don’t go to my … Read More “DNS requests to .x69 and .xbf domain” »

Hello, I read a bit about both and am unsure where DNS resolvers usually are implemented. Does anyone know with validated source? submitted by /u/DramaticEducator6276 [link] [comments] Powered by WPeMatico

I’m testing unbound as recursive resolver on my macbook air. When I use it at my office or when connecting to the internet through my mobile hotspot it is working flawlessly. When at home and connected to my LAN wi-fi it just stops working. There must be something wrong with my router and dnssec specification. … Read More “Unbound issue” »

“The reverse DNS database of the Internet is rooted in the .arpa top-level domain.” From the “Reverse DNS Lookup” Wikipedia page. What does this mean? I thought that, simply, my dns zone file will have a PTR record written in it. Why does .arpa have to come into it. Does this happen with every record … Read More “Confusion Around Funermental DNS Concept” »

Back in 2021, Facebook and its related sites went offline for a while because of a BGP issue that prevented access to their authoritative DNS servers. I always thought that public resolver services (not the same as authoritative) used multiple IP addresses with separate ASNs to maximise resiliency so that if internet routing for one … Read More “Public DNS Resolver ASN Question” »

Running Windows Server 2022 We have multiple sites each with their respective domain controllers. The domain controllers have bgp peering with the local cores that act as RR servers with all distribution and routed access nodes as RR clients. When following the windows guide there are certain settings that appear to be intended to not … Read More “DNS Anycast across multiple sites causing replication issues” »

So I have two DNS servers running different versions of Bind, and they are answering differently on a classless reverse DNS query, despite what I think are very similar configurations, and I’m not sure why or if this is a problem. They are both non-recursive authoritative servers. For reverse DNS, we host both the class … Read More “Classless reverse DNS – direct host query returns CNAME, not PTR” »
