Get your ASP.NET Core application running on a Windows VPS with IIS. Follow the OrnekWeb example from Hosting Bundle installation and Release publishing through app pool permissions, HTTPS, startup diagnostics and rollback.
Deleting an exposed SSL private key does not invalidate copies. Follow an Ubuntu and Nginx walkthrough to contain the leak, generate a new key, deploy and verify its certificate, revoke affected certificates and prevent another exposure.
Learn how to use SSH agent forwarding for Git deployments on a VPS without copying your private key, while limiting exposure and troubleshooting failures.
How To?
Practical hosting guides help you diagnose problems, plan changes, and check the result. Use the resources below to choose a starting point for DNS troubleshooting, WordPress maintenance, or VPS security. Each task needs a different approach: identify the affected service before changing settings, and keep a record of what you change.
Find out why a domain does not resolve. Start with the DNS troubleshooting guide when a browser reports DNS_PROBE_FINISHED_NXDOMAIN or cannot find your website. Check the domain’s nameservers and authoritative DNS records, then compare the answers returned by your local resolver. This helps distinguish a record problem from a cached response before you edit a working configuration.
Investigate WordPress database overhead. The WordPress database optimization guide explains wp_options, autoloaded data, and table bloat. Take a database backup before cleanup, identify which plugin owns a setting, and test changes on a staging copy when possible. Removing an unfamiliar option can break a feature even when its name looks obsolete.
Strengthen access to a VPS. Follow the VPS security hardening checklist for SSH settings, Fail2ban, and updates. Confirm that key authentication works for a separate administrative account before restricting root or password access. Keep an existing session open and make sure you can reach the server through its recovery console.
Check the outcome and keep a recovery path. After each change, repeat the original test and inspect the relevant logs. For DNS, compare lookup results; for WordPress, test important pages and forms; for SSH, open a new connection before closing the old one. If the result is unexpected, restore the previous configuration and investigate one change at a time. Record the successful steps so future maintenance is easier to repeat.

Increasing IPv6 Adoption Rates Worldwide
IPv6 adoption is finally moving from niche network projects to mainstream infrastructure planning, but the global picture is still uneven. Some countries already serve most traffic over IPv6, while others barely route a single packet. For hosting customers, network operators, and IT teams, this gap matters: it affects costs, performance, long‑term routing strategy, and even…

Rising Prices of IPv4 Addresses Due to Shortage
IPv4 addresses have quietly turned into one of the most expensive building blocks of the internet. Over the last few years, we’ve watched their cost climb from a background line item on hosting invoices to a strategic topic in budget meetings. If you manage websites, SaaS products, email infrastructure or customer hosting plans, you are…

VPS Provider Mergers: What They Mean for Your Servers and What To Do Next
VPS provider mergers are no longer rare headlines you can ignore. Consolidation is reshaping the hosting market: brands disappear, platforms are unified, data centers are closed or opened in new regions, and pricing models quietly change. If your business runs on virtual servers, every one of these moves can affect uptime, latency, support quality, compliance…

Why IPv4 Address Costs Keep Rising (And How to Respond)
If you manage hosting, networks, domains or servers, you have probably noticed a line in your budget that keeps creeping upward: IPv4 addresses. A few years ago, public IPv4s felt like a routine, almost negligible cost. Today, they are a strategic resource that can materially change the economics of a project, a SaaS platform or…

Accelerating IPv6 Adoption in Your Network
IPv6 adoption is no longer a forward-looking experiment; it is a practical response to very real IPv4 scarcity, rising address costs and the need for a cleaner, more scalable network architecture. Many teams we speak with at dchost.com are already convinced that IPv6 is the future, yet their networks remain mostly IPv4‑only or limited to…
