Free DNS Server and Free Web Hosting Service
ZoneEdit.com offers free DNS server for up to five domains, with which you may host your own web sites at home. They also have an open-source program that automatically updates your DNS records with your (typically) dynamic IP address obtained from your Cable/DSL internet provider. A DNS server is essential in helping the visitors to visit your web site's physical machine (your PC at home in this case) according to your web site's name (such as www.jihe.net).
For hobby web site owners that care less about technical issues, you may additionally choose MemeBot for free web hosting. The catch is, in order to get the free hosting, the web site needs to be smaller than 30MB on disk and the monthly bandwidth (amount of data transfered from/to the web site) needs to be below 100MB.
