What is an A Record? The A in A record stands for Address. An A record is used to find the address of a computer that is connected to the internet from a name. If you are visiting a website, send an email or connect to Facebook or do anything on the internet, the address you enter is a word that is connected with dots.
What are A records?
A record will map a fully qualified domain name to an IP address and that are most often used record type in any DNS configuration. Address records can be configured in a domain for a specific host like www.example.com or sometimes it will represent with an @ symbol.
With communication being essential in today’s day and age, choosing the right email server is vital. When it comes to the best servers like Smartermail and Mailenable, we strive to deeply evaluate features in order to see which is the most exclusive, down to the tee.
SmarterMail, an award-winning service, is currently benefiting small businesses and large corporate organizations with the most flexible and reliable email server available, giving administrators and users more control over the accounts.
When migrating a website from a previous provider, it is important to test out the site while in development to ensure a smooth transition. If a website is incorrectly migrated, you can run the risk of losing not only functionality but also traffic and search visibility. Common issues that can persist following the move of all data, databases and emails are:
- Contact/Enquiry Forms – Commonly, these forms use customized parameters and components that most likely won’t exist within your new server. Furthermore, mail scripts can present a problem by specifying an SMTP mail server that is not compatible with the new host.
- PHP and Module Version Differences – Identify the prerequisites of your site by using a simple PHP info script. You can then deploy a system that will be qualified to run your existing service.
- Permissions – All custom permissions must be present to ensure no loss of functionality during an FTP migration. Plesk migrations can be used to guarantee all permissions and setting are transferred. Free migration services are offered by certain providers.
Following a sound migration process will give you the best chance at identifying issues quickly to relieve a lot of pressure and frustration.
Email spamming is an ever present issue that can cost you or your business time and money. It is surprisingly easy for email addresses and computers to be hijacked for spamming purposes. Here are steps you can take to increase security and ensure you stay off the blacklist.
- Make sure your computer is free of viruses. Many free anti-virus programs are on the market. Find one, make sure it is updated and scan your computer.
- Starting fresh is important if you believe your computer or accounts have been compromised. Reset your passwords – this includes email passwords.
- Use strong passwords as preventative measures. Strong passwords usually contain a combination of the following: Uppercase and lowercase letters, numbers, and punctuation.
- Don’t store passwords. This includes storing on your browser, FTP client or email client.
- Keep your passwords secret. Passwords are important and should not be shared with anyone.
- Test your computer for keystroke loggers or spyware to ensure passwords stay secret.
- Third party applications and plugins that aren’t updated are vulnerable to penetration
- Protect servers and websites by regularly scanning with maldet (linux) or clamwin (windows).
Whenever you type a website address into your browser, the address (say for example the web address: (www.domainnamehere.com) is translated into a set of numbers, known as an “IP address” (the IP stands for internet protocol). So whenever you type a domain name into your browser your computer is actually directed to the IP address that the domain name is associated with.
Every site on the internet has an IP address, and every site can be reached by typing in its IP address, with some exceptions. Some websites on the internet will be hosted on the same server, which means they will have the same IP address. So for example, two websites like www.hisname.com and www.hername.com may be hosted on the same server; in which case a person looking for one of these sites will be routed to the appropriate site by the server. In cases like this, where more than one site uses the same IP, the IP address will be known as a “Shared IP address”. If a website has its own unique IP address that no one else uses, then that IP address will be known as a “unique IP address.”
When browsing the internet you may have gotten the occasional popup informing you that the site you want to browse has a security certificate that is not trustworthy; other variants may include: “the security certificate presented by this site is not trusted” or “the security certificate used by this site was not issued by a trusted certificate authority.” These are known as SSL errors (Secure Socket Layer errors). The message you get informing you of the SSL error will vary depending on the browser you are using.
SSL Certificates are necessary for those sites where a user is supposed to submit highly private and confidential information. It augments the website’s security and prevents imposters from doing fraud under your website’s name.
These certificates are of different types. Some organizations need SSL certificate for encryption only, while others need to exhibit their integrity and want to build a stable and reliable relationship with customers. So which SSL certificate will be best for your website? Here are the three different types of SSL Certificates which can help you determine the right choice for your website.
A common issue when hosting a website on a shared server is: do you need to use a dedicated IP address? Why not just stick with the shared IP address? A dedicated one offers many advantages, but let’s look at the definitions first.
IP — Internet Protocol — is a unique address given to each computer connected to a network. It’s used to identify a location of a specific machine or a website. In our case, your website.
A shared IP address is a single address shared by multiple websites on a single web server. A dedicated IP address is used by just one website, which can then be accessed either by its domain name or directly by its IP address.
If you have a website, whether for business or leisure, you may have found certain days where your website just doesn’t load. There could be an array of reasons for this which includes elements such as:
The website domain name could be expired
Many people think your domain name needs a registration and thereafter, all is good. However, your domain needs to be renewed on an annual basis. If you cannot access your website, visit the website called who.is and punch in your domain name. This will generate a status update to let you know if your domain name needs to be renewed and if it does, contact your domain registrar. Should this be the issue, simply pay the outstanding amount and your registrar will reactivate your domain and your website will be back up and running.
HTTP status and error codes are responses that are given by the website servers. The status codes are informational codes while HTTP error codes show an error.
The purpose of these codes is to communicate the cause of the issue so that it can be resolved. You must have seen most of these codes on the internet while browsing like HTTP 404, HTTP 500 and others.
Every HTTP status and error code has two parts:
- The code (such as HTTP 404)
- The reason phrase (such as Not found)
The phrases are simple phrases that explain the code and are helpful in making sense of the code. For instance, an HTTP 404 error code doesn’t make much sense but HTTP 404 Page Not Found makes sense that the page on the website is not found.
