Tips, tricks and tools to manage your hosting, web server, domain names, websites, web analytics.
An IP (Internet Protocol) address is a unique code that identifies a piece of equipment connected to a network. These addresses are used in messages between network devices like the network or wireless card in your computer, the equipment from your ISP (internet service provider), and all pieces of equipment between your machine and the one your computer needs to talk to.
DNS stands for Domain Name System. It is used to point memorable domain name towards the IP address of the server. This allows you to change web hosting without changing your domain name. Each website has a specific IP address, and the DNS records pair that IP address to the domain.
The Base64 is a binary-to-text encoding that represents binary data in an ASCII string format by translating it into a radix-64 representation. Each Base64 digit represents exactly 6 bits of data. Therefore, three 8-bit bytes (total of 24 bits) can be represented by four 6-bit Base64 digits.
VestaCP is a free and open-source alternative to cPanel. After installing Vesta Control Panel on your Linux server, point your domain name or subdomain to your server's Name Server records.
The Apache module mod_rewrite allows you to rewrite URL requests that come into your server. It is based on a regular-expression parser. When the url in your browser's location bar stays the same for a request, it is an internal rewrite, when the url changes, it is an external redirection.
Internet Protocol version 4 (IPv4) is the fourth version in the development of the Internet Protocol (IP) and the first version of the protocol to be widely deployed. IPv4 is described in IETF publication RFC 791 (September 1981), replacing an earlier definition (RFC 760, January 1980).
When you visit a web page, your computer’s web browser communicates with the web server of the website. Your web browser, also known as the client, submits a request to the web server for web page to be delivered. The web server always returns a reply in the form of response code or status codes.
If you are facing problems with your internet connection, or if you are not able to open websites even though internet is connected, or if there are some network or DNS problems, then in Windows 8, 7 or Vista, you can use ipconfig command and try to solve your problem.
The URL Inspection tool provides information about Google's indexed version of a specific page or URL. You can inspect both AMP and non-AMP URLs. If the page has alternate versions, the tool also provides information about the canonical version. This tool describes the most recently indexed version of a page, not the live version on the web.
This report shows the indexing state of all URLs that Google has visited, or tried to visit, in your property. The summary page shows the results grouped by status (error, warning, or valid) and reason. You can click on a table row to see all URLs with the same status or reason and see more details about the issue.
There are three types of render-blocking URLs: scripts, stylesheets, and HTML imports. These URLs block the first paint of your page. Your goal should be to reduce the impact of these render-blocking URLs by inlining critical resources, deferring non-critical resources, and removing anything unused.
The Performance report shows important metrics about how your site performs in Google Search results: how often it comes up; average position in search results; click through rate; and any special features (such as rich results) associated with your results.
DKIM validates a domain name identity that is associated with a message through cryptographic authentication. DKIM attaches a new domain name identifier to a message's header to validate authorization for its presence. The identifier is independent of any other identifier in the message.
When an email is sent or received, there is no clear indication that the email is authentic or if it was sent from a validated sender address or domain. One way to improve email security is the DMARC standard.
The Sender Policy Framework (SPF) prevents sender address forgery. It protects the envelope sender address, which is used for the delivery of messages. SPF allows the owner of a domain to specify mail sending policy like which mail servers they use to send mail from their domain.
