The captive portal technique forces an HTTP client on a network to see a special web page (usually for authentication purposes) before using the Internet normally. A captive portal turns a Web browser into an authentication device. [ 1 ] This is done by intercepting all packets , regardless of address or port, until the user opens a browser and tries to access the Internet. At that time the browser is redirected to a web page which may require authentication and/or payment , or simply display an acceptable use policy and require the user to agree. Captive portals are used at many Wi-Fi hotspots , and can be used to control wired access (e.g. apartment houses, hotel rooms, business centers, "open" Ethernet jacks) as well. Since the login page itself must be presented to the client, either that login page is locally stored in the gateway , or the web server hosting that page must be " whitelisted " via a walled garden to bypass the authentication pr...

Dynamic DNS or DDNS is a term used for the updating in real time of Internet Domain Name System (DNS) name servers to keep the active DNS configuration of their hostnames, addresses and other information up to date. The term is used in two contexts which, while technically similar, have very different purposes and user populations. Administrators who maintain the Internet, and those who are associated with domains, use networked devices, [ clarification needed ] such as routers and computer systems using the Internet Protocol Suite , to keep DNS server information up to date for the proper functioning of the Internet, and uninterrupted access to devices and services whose numeric IP address may change. This process is dynamic DNS updating . The Secure DNS Update protocol discussed in RFC 2136 may be used. http://dyn.com/dns/ http://www.no-ip.com/ http://www.dnsexit.com/ Name URL and domain selection Subdomains?
