Due to the nature of the existing setup, we’re doing delegated DNS and CNAMEs on Windows Server DNS to point certain resources at the F5 resolvers. In order to accurately do topology load balancing, we’re wanting to use the ends0/client subnet feature. However, I’m … Read More “EDNS0 Issues – Windows DNS Client (Win10)/Server (2016)” »
I want to ensure that a list of domains of API endpoints that are called randomly and sometimes infrequently are always cached locally to minimize response time in a server application. Is there a way with unbound that I can make it so unbound automatically re-fetches api1.example1.com and api2.example2.com before their TTL (time-to-live) expires within … Read More “With unbound, is there a way to ensure a specific domain is always loaded/cached locally?” »

Previously @Xhospitality.co.in email was redirecting to google mail accounts. Due to the change of nameserver to Hostinger, the email stopped redirecting to Gmail So —> I … Read More “.co.in & .in sites with GoDaddy” »

Since I’m learning about how DNS and other web stuff works currently, I’m interested to know why www is a common standard subdomain for websites. For example, if you were to go to apple.com, it would redirect to www.apple.com. What’s the point of this? I also apparently made the mistake of doing this backwards where … Read More “Why is the www subdomain a common standard?” »
I’m going to try and anonymise this if possible, but I’ve got a dynamic DNS service running for my ASUS home router – since my ISP assigns me a dynamic IP. Let’s called the dynamicDNS service: test.asuscomm.com Now I’ve registered a domain, let’s call it, example.co.uk and the DNS records are as such that it … Read More “when I drop the www from my domain -it does not work… CNAME record?” »
