Hello sir/madam,
I very much enjoy and feel really satisfied with taking your networking course here in connected dots. All the courses, modules, and chapters are very nice!!!

My question is why can't your connected dots organization provide a certificate for finishing a course here in connected dots? My humble suggestion is u can provide a certificate for the learners in order to appreciate learners like me and also it will be very useful to show in our college and for us to apply for an internship related to this field, for in interviews and useful for learners to showcase their learning on social platforms like LinkedIn. I feel many learners will feel appreciated and motivated to enthusiastically continue their learning further with other courses !!!!

This is my humble request, consider this if possible do the needful for us. Thanks in advance !!!


And it is easy for your organization at this lockdown time to do this for your learners who completed a particular course as they have a registered account in your organization. Consider this. Thank you!!!!

Hi Narendira, thank you for your feedback, and for bringing up the point about issuing a certificate. In the very near future, there will be a certificate available for everyone that completes Courses 1 to 6. There will be some criteria for the certificate (minimum scores on certain test/exercises and completion of all lessons). This should be available soon after Course 6 is complete (there are still 2-3 more lessons to publish for Course 6.)

ok, then fine thanks a lot !!!!

Do you know any website like yours where I can learn programming interactively (in the same way you teach networking).
If you could tell it would be a great help for me.

HI Jashan,
For programming, you could perhaps try a website like https://www.codecademy.com/

WHAT IS THIS 192.168.45.1/32) WHEN WE COMPARE CISCO IOS VERSIONS? IS THIS IS OUR GATEWAY ? WHY IT HAS SUBNETTED WITH /32 CIDR VALUE?
I HAVE COPIED THE TEXT BELOW

The highlighted line in the Cisco 2911's output tells us that:
The Class C network 192.168.45.0 has been subnetted into smaller subnets with 2 different Subnet Masks (/25 and /32)
2 of those subnets (192.168.45.0/25 and 192.168.45.1/32) exist in the Routing Table.
Connected Dots Online4 years ago
Hi Rajneesh,
The /32 entries in the Routing Table in IOS 15 simply list out the IP Addresses of the connected interfaces.
In IOS 12, the routing table would include only the connected networks, you would have to use a command such as "show ip interface brief" to figure out the IP Address assigned to an interface.
In IOS 15, there is one entry for a connected network and a 2nd (/32) entry that indicates what IP Address is assigned to the interface that is connected to that network.
Does that help make things clearer?
