How to ask my question but obfuscate my real data I asked one question about my DNS records and was forced to substitute my real domain name and IP with fake data like 111.111.111.111 & bar.com. One user didn't welcome that and made me -1, so I deleted the question. My server is still very vulnerable, I am on setup phase. What do I have to do to ask my question ?

First, one point: if you are basing your server's security on people from the internet not "finding" your server, you've already lost. If your server is vulnerable, then you should implement firewall rules to limit traffic to the server until you get the issues sorted out.

There are some topics, particularly those that are DNS-related that are extremely difficult to answer without knowing the domain name in question. In cases such as these, your options are:

1. Post the domain name after doing whatever you need to do to secure your server assets (which you should have already done anyway).
2. Purchase a placeholder domain and configure it **identically** to your real domain, then replicate the problem on that domain and post the placeholder domain in your question.
3. Hire a professional to help you out.
