The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

IP Address vs Subnet Mask

Asked by tjie in Networking Protocols, Dynamic Host Configuration Protocol (DHCP), TCP/IP

Hi,
1) I see at one of DHCP configuration as follows: i) The Scope's Name: LAN A, ii) Start IP  address: 10.1.1.1, iii) End IP Address: 10.1.1.254, iv) Length: 24 (so the Subnet Mask: 255.255.255.0)
2) This configuration is working properly (I can see the computers which use this IP address can communicate very well; but i am not sure this is only working for INTRANET setting only)
3) However, i am still CONFUSED
4) My confusion: i) The above IP addresses (10.1.1.1 to 10.1.1.254) are a Class A IP address, RIGHT?, ii) And the Subnet Mask: 255.255.255.0 are the Subnet Mask for Class C IP address, Right?
5) My Question: i) Why these IP addresses of Class A are working well with the Subnet Mask of Class C?, ii) Is this configuration working because of the INTRANET  Configuration ? [Maybe, For INTRANET we can create  "any different Virtual LAN? ( i am not sure as i have not yet experienced with VLAN itself; this is just my guessing)]
6) Any help? ( I need the Explanation from someone who has experienced with this; not just "throwing the Wikipedia things")
7) Thank you
