Information about DNS and network
When trying to switch webhosts recently, I routed my domain root to a CNAME entry in DNS. I figured since mail was handled via MX records, it would be unaffected. Today, the postmaster returned a delivery delayed to <myusername>@<cname-value> instead of my actual email address. Do CNAME entries trump MX records in DNS, or is … Read More “CNAME question” »
I’m looking for a way, preferably that runs in a unix-like environment that can do a recursive lookup and then manipulate the answer, for instance, replace something in ip-number. For instance: 1 – Client looks up yada001.hello.local 2 – The clients selected recursor asks a DNS server that returns yada001.hello.local: 10.10.10.5 3 – A rule … Read More “Rewrite answers from the recursor?” »

I can’t find any way to actually create a master zone from the shell. Its a bit tedious to have to run sql queries and set them to … Read More “PowerDNS 4 and pdnsutil – only creates native zones?” »

I’m trying to troubleshoot an existing system and am unclear what happens here. IN DNS there is one service pointing to two servers with same priority and weight. How are queries/connections managed/balanced? Do all go to one or is there a logic for this? For example : _service._on.my.host 60 IN SRV 0 100 5063 a.host … Read More “Multiple SRV same priority and Weight – what happens?” »
