Information about DNS and network
I believe what I am wanting to do is not possible with DNS. I migrated our old intranet site to a new web server running WAMP. It was in the www root on the old server, but there are multiple sites on the new server so I placed it in its own folder for organization. … Read More “Host Record To Redirect WAMP root to site in sub-folder” »
I noticed on 8/18 that I couldn’t reach ada.gov. Had another friend in San Diego, also using Cox test. No dice for him either. If I run my VPN, I can reach it. Since then, I’ve found somebody using another ISP, elsewhere in CA who can’t reach the site. After several calls/chats, Cox said it … Read More “ADA.gov unreachable by many. Routing problem?

Can i have the same host for two records with different data? Example: m1._domainkey.domain.com -> k=rsa; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCxvdvLZXbCuLGPa7sckTeJp49zTWfSEj/FSboL+eASwli5QoEloH64vKZmjUmpnvaAws2w1+Y8p0In0f+8CcNRGDUTpbt4dVtYo0JXHJX43ezhYqlj3SYyefSIjwOEpv+g7xyGQaeSpFwZFUDjTvg9hHNGY+QiSNKfUqitF+JccwIDAQAB and m1._domainkey@domain.pt -> k=rsa; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCfMYhHO16+RBGXmDSEQRc/okh6uz3034DwcH8X59ilLO9AC/NN8AKTWwQsYhvn/WHzHhCherU7tNioFW2lTMKknIbnos3PHCvGFUpWjAjieP53c2izNz1VJvLehYdpn89C4zEgYMfB2p70lnwBv6T5HoWUeljRhOP13l69UD2HUwIDAQAB submitted by /u/sonya_7 [link] [comments] Powered by WPeMatico
I run DNS on a VPS for myself and a few friends. Due to having too many cooks in the kitchen, we left unbound accepting from 0.0.0.0. Now I’m getting crushed by DNS lookups for the traditional “big” response names…. but from many many sources. ELI5 – am I part of a DDoS against 100s … Read More “ELI5 – why is a DNS amplification attack against many sources a thing?” »

I am troubleshooting a very strange DNS resolution issue, I’m running a DNS server using PowerDNS (pdns.x86_64 3.4.11-1.el7), and when querying domains hosted on the server through the OpenDNS public resolver (208.67.222.222), I get a SERVFAIL sometimes. This does not seem to happen with other resolvers. Here is how you can reproduce the issue: watch … Read More “PowerDNS Weird Resolution Problem” »
used to, I would simply change (on Mac FYI) my DNS server to google’s public ones and BAM problem solved. Now when I try that, my browser gives me a message saying that it cannot connect to the DNS. Can anybody help me with this? submitted by /u/mr_sc00ty [link] [comments] Powered by WPeMatico
Given a record or records, how do I tell what is the parent zone but isn’t a TLD, gTLD or second level domain? E.g.: www.example.com test.www.example.com www.example.co.jp wibble.example.fnd.br I am trying to write code for this and I’m not sure how to it normally using DNS / Whois. I’ve seen some code which naïvely assumed … Read More “Trace a record back to it’s zone.” »
I recently moved a website to a new host and updated the nameservers, but found I couldn’t access the site. After a fair amount of troubleshooting it turns out our ISPs DNS (Virgin) won’t resolve the name servers – I realised this after changing to the open DNS on my computer which resolved the problem … Read More “Website not accessible through virgin DNS” »
Based on what I read on their site, it’s basically similar to Cloudflare’s CNAME flattening? Is that correct? submitted by /u/zylai [link] [comments] Powered by WPeMatico
