Domain names are created to make IP addresses easy to remember. Every computer has an IP address assigned to it - much like a street address. But instead of having to memorize each IP address number, we assign domain names to these numbers so we can easily remember them. The domain name system, or DNS, takes domain names and translates them into their IP addresses so that computers can communicate with one another.
We’ll be looking at this list several times a year, so keep an eye out for us re-opening the survey for hosts to submit themselves for inclusion. Listing is completely arbitrary, but includes criteria like: contributions to WordPress.org, size of customer base, ease of WP auto-install and auto-upgrades, avoiding GPL violations, design, tone, historical perception, using the correct logo, capitalizing WordPress correctly, not blaming us if you have a security issue, and up-to-date system software.
You gain the most web-building functionality if you create a self-hosted site. This typically involves transfering the free WordPress CMS to server or signing up for a web host's optimized WordPress plan. With an optimized plan, the host automatically handles backend stuff, so you don't have to worry about updating the plug-ins and CMS, and enabling automatic backups. In these instances, the WordPress environment typically comes pre-installed on the server.
Note: The dual meanings "host"/"guest" of Latin hospes and its progeny are due to customs of reciprocity: a person serving as guest on one occasion would act—and be expected to act—as host on another occasion to a visiting former host. Both Latin hospes and Slavic gospodĭ have undergone a considerable degree of phonetic reduction from their putative etymons—in particular in the Slavic case, where Latin unstressed syllable reduction and syncope were not at play—leading some to question the correctness of the etymologies. Parallel compounds with the same second element are Greek despótēs "master, lord" (going back to *dems-pot- "master of the house"; see despot), Sanskrit dámpatiḥ "householder, lord of the house," Avestan də̄ṇg paitiš; Sanskrit viśpátiḥ "chief of a settlement/tribe," Avestan vīspaitiš, Lithuanian viẽšpats "lord" (with outcomes of Indo-European *u̯iḱ-, *u̯oiḱ- "house, community"; see vicinity).
For plans or packages featuring unlimited websites, domains, or email accounts, we do not enforce any official limitations. Customers are able to utilize as many of these features as they wish. That said, these are of course not infinite resources and there are inherent maximums associated with the technology powering them. For example, while email account creation is unlimited, these rely on the file storage available on the account. Therefore customers need to be operating within the Terms of Service to ensure resources are available to fully enable email functionality. Customers operating within the Terms of Service have yet to come up against technical boundaries for email, domains, or websites.
Another recurring theme in our reviews is the talk of unlimited hosting — domains, storage, email, bandwidth, databases, and other tools. The truth is, however, when a host boasts unlimited storage or site traffic, they really mean they’ll allow you to use as much as you want — to a point. Yes, there are limits to unlimited, but chances are you’ll never get anywhere near that ceiling. Furthermore, the most reliable web hosts will give you a heads up when you’re approaching the maximum and start talking to you about your options for scaling.
That said, not all web hosts offer email. WP Engine, for example, does not. In such instances, you must email accounts from a company other than your web host. GoDaddy, for instance, sells email packages starting at $3.49 per user, per month. That might sound like a hassle, and just one more thing to keep track of, but there are actually some webmasters who feel that separating your email hosting and web hosting services is smart. That way, one provider going offline won't completely bork your business.
There are free web hosting available, but almost all of them have some sort of catch. Usually, you can find free WordPress hosting being offered in online forums or small groups. In most cases, these are managed by an individual who is reselling a small part of his server space to cover up some revenue. Often the catch is that you have to put their banner ads on the site. Some may ask you to put a text link in the footer of your site. These folks will sell that banner ad or text link to cover up the cost of your free space along with pocketing the profits. The biggest downside of having a free host aside from the ads is that they are unreliable. You never know when this person will stop offering the free service. They can leave you hanging at any time. If you are serious about your website or business, then avoid Free WordPress hosting at all costs.
WordPress.org references the open-source (free) software that can be downloaded and installed pretty easily, particularly if you have a web host that makes this process a breeze. Self-hosted WordPress allows you to capitalize on the robust offerings of the established content management system, plus the potential for more features, such as a free domain, unlimited email accounts, marketing credits, and expert support).
