Is it possible for:
1. The server (possibly dedicated) to remain undetectable (IP, location, etc.).
2. A domain that conceals any information about the server (as mentioned above) and myself (such as credit card number or personal details) from knowledgeable and authorized individuals...

Can this be achieved?
If yes, how (optional in the PM)?
If not, why?

Based on paragraph 2, it is important to consider the domains ending with .tk. If you refrain from inheriting them during registration, it becomes possible to retain anonymity.

Additionally, it is crucial to be cautious of the information shared online and take necessary steps to protect personal privacy. It is always advisable to review and understand the terms and conditions of any online services utilized, especially when it comes to data protection and anonymity.

And whom do you intend to conceal it from? If your intention is to hide something from law enforcement, then I strongly recommend that you abandon the idea altogether.

Based on your inquiry, it appears that you lack a comprehensive understanding of how the Internet operates. Even if you were to successfully "hide" the server, you would likely encounter issues or leave traces through seemingly insignificant details, long before having an opportunity to engage in any malicious activities using said server.

By not including the site in the search engine's index, it will remain undiscoverable. Additionally, you can enhance security measures by employing IP filtering, utilizing non-standard ports, and disabling ICMP echo if you possess a dedicated IP. These precautions help mitigate risks. For example, if someone were to scan your ports and identify a specific port (e.g., 3210), any connection attempts would result in a "Connection refused" error.

It's important to address the technical feasibility and practical limitations of achieving complete invisibility for a server and domain.

1. Anonymizing the Server:
Technically, it is possible to utilize various techniques to obfuscate the true IP address and location of a server. These techniques include using virtual private networks (VPNs) to route traffic through intermediary servers, utilizing proxy servers to hide the origin of requests, and leveraging the Tor network for anonymous communication. Additionally, employing techniques such as IP address spoofing and network address translation (NAT) can further obfuscate the true origin of network traffic.

However, it's crucial to understand that no method can guarantee absolute invisibility. Determined adversaries with advanced technical capabilities and significant resources may still be able to conduct sophisticated network analysis to uncover the true IP and location of the server. Furthermore, the use of these anonymization techniques may raise suspicions and attract unwanted attention from network administrators, law enforcement agencies, or other entities.

2. Concealing Domain Information:
When it comes to concealing information about the domain and its ownership, it's important to recognize the limitations of domain privacy services. Domain privacy services offer the capability to mask the personal contact information of the domain owner in the publicly accessible WHOIS database. While this provides a layer of privacy, it does not guarantee complete anonymity, as law enforcement and authorized individuals can still request access to the underlying ownership information from domain registrars.

Moreover, concealing personal information such as credit card numbers and other sensitive details from knowledgeable and authorized individuals should primarily be addressed through robust cybersecurity measures implemented on the server itself. This includes utilizing encryption to protect data in transit and at rest, implementing secure authentication mechanisms, and maintaining strong access controls to prevent unauthorized access to sensitive information.

From an ethical standpoint, it's important to recognize the potential consequences and responsibilities associated with attempting to achieve complete invisibility. While privacy and security are legitimate concerns, it's crucial to balance them with ethical considerations and legal compliance. Engaging in activities that seek total invisibility may raise ethical questions about accountability, transparency, and compliance with laws and regulations.
