Before starting work with the services previously described (OpenDNS, DynDns) it is necessary to define what type of IP configuration will be used.
ISP’s can supply two types of IP configuration: dynamic IP and/or fixed IP.
Fixed IP implies that user will have always the same IP address assigned to it while dynamic IP implies that user might have a different set of IP’s assigned to it based on user demand and IP expiration.
Fixed IP’s are more suitable, I mean, easier to configure, for building the IAPC but dynamic IP can also be consider. In fact most of the ISP’s nowadays are using dynamic IP type configuration.
Overview:
What IAPC implementation does is to change from the ISP’s supplied DNS IP server to the OpenDNS IP server. This causes every user request to access Web content to be routed to the OpenDNS server which performs a Web-content filtering procedure as well as others features.
To perform this operation, OpenDNS needs to know who is requesting DNS information. In other words, OpenDNS needs to know user IP address to be able to apply pre-defined Web-content filtering.
Fixed IP:If you are configured as Fixed IP, OpenDNS configuration is pretty straight forward and is described in 3 steps:
Step 1: Change DNS on user
system;
Step 2: Create an OpenDNS
user account;
Step 3: Customize.
Those steps can be followed here. There is a very clear explanation (a lot of pictures) showing how to configure every parameter in user system as well as in OpenDNS.
Dynamic IP configuration will be present on IAPC Part II.
Guide to setup an efficient and secure Internet Access Parental Control.
Basic idea is to restrict Internet Access to sites that might contain offensive or inappropriate content such as pornography, racism, cracks and so forth.
Classification of the abusive content is based on the moderator decision as well as automatic fashion.
Below is a list of the services that will be put together to accomplish the Internet Access Parental Control:
OpenDNS - world's largest, fastest-growing DNS service provider. Millions of people worldwide (and growing) trust us to handle their DNS and Web-content filtering needs.
DynDNS - Provides services that help user and content providers keep connected.
As you may notice, this solution is based on the DNS (Domain Name Service) - The Internet system that translates human-understandable hostnames (like www.dyndns.com) into computer-understandable IP addresses (like 63.208.196.66) and back again.
