WordPress 3 Ultimate Security
Let's take some time out to prep up on the Domain Name System and some of its lingo.
Locally, we type a uniform resource locator into a web browser, rather like this:
http://www.somesite.com/somefolder/somefile.html
Setting aside the tidy/separators, here's the breakdown of a URL:
http – The protocol, in this case Hyper Text Transfer Protocol, that we want parsed. Alternative protocols include ftp, https, and mailto.
www – The hostname or sub-domain that distinguishes one network element from another. You could equally use, say, mypc for a PC, dlink for a router, mail for webmail, or blog for a sub-site.
somesite – This is the network or domain to which hosts belong. You could use an IP address instead.
com – com is one of many top level domains to which we attach a domain.
Finally we have a file, somefile.html, buried in a directory tree and it is this that we are telling http, having resolved the journey, to bring home and parse.
So how does the Domain Name...
