Taking Your Site PublicwithDynamic DNSYou can make your Web site public by renting serverspace from an ISP or by obtaining your own domainname and hosting the site from your Apache server. When you rent machine space from an ISP, you paynot only for the room your data takes up, but alsofor the Web traffic to your site. If you have a smalland simple site with little traffic, that s not a prob- lem. If you have a large or complex site with a lot oftraffic, renting server space can get costly. You can save time and money by runninghigh-maintenance Web sites on local machines. If you use PHP to build your site or have livedatabase access from the site, keeping thedata where it can be updated easily is a realtimesaver. In order for others to find your Web site, you have tohave a host name, and the host name must be fullyqualified that is, your host name must include adomain name (something like www.example.com). Ifyour ISP is willing to assign you a fully qualified hostname, you re good to go. If not, don t despair youcan borrow someone s domain name by usingdynamic DNS. Understanding how dynamic DNS worksWhen a user surfs to your spanking new Web site, hetypes a name (say www.example.com). His Web browserasks a name server to convert the site name into anIP address. His local name server defers the requestto a well-known name server somewhere on theInternet. Eventually, the name server chain locates aserver that s responsible for the example.comdomain. That name server returns the IP address for host www(that is, host wwwwithin the example.comdomain). A normal name server maintains a database thatconverts host names into IP addresses for the hostson the name server s local network. A dynamic DNSserver provides the same service (host name to IPaddress translation), but it lets you change the data- base. To use a dynamic DNS server, you send your IPaddress and desired host name to the server, and itagrees to give out your IP address whenever some- one asks for your fully qualified host name. Of course, the domain name that you get to use is owned by thedynamic DNS provider, but it gives you a permanent, fully qualified name that you can hand out to friendsand business partners (without purchasing a domainname for yourself). What happens if your Internet service providerchanges your IP address? Simple just update thedynamic DNS database. Setting up dynamic DNSTo use dynamic DNS, you first contact a company(often an ISP) that will register your site name. Youcan find quite a few free (and paid) dynamic DNSproviders online. Each service provider has its own how-to s forsetting up a dynamic DNS service.
