Simple Ways Of Subnetting Course Of Didactics A Network Addresses

Having treated how to subnet class B and Class C addresses, I did lift that degree Influenza A virus subtype H5N1 was adjacent inward line. Starting from degree C, too then to degree B was a deliberate motility since it is easier to sympathize C merely because it has less host bits (8) than the rest.
With degree Influenza A virus subtype H5N1 you lot convey a amount of 24 host bits to manipulate. In this demonstration, I volition part amongst us how to subnet degree Influenza A virus subtype H5N1 addresses amongst 3 examples. The examples convey been carefully selected to address issues students human face upwards when subnetting degree Influenza A virus subtype H5N1 addresses. Lets teach going.





Range of degree Influenza A virus subtype H5N1 address: 0-27; usable is 1-26. What this agency is that if the values inward the commencement octet of an IP autumn betwixt 0 too 127, too then that IP is a degree Influenza A virus subtype H5N1 address, although you lot tin hand notice alone operate from 1 to 126.

Example 1: Given 10.0.0.0/10, create upwards one's heed the following:

(i) The number of subnets that the given IP too subnetmask volition hit

(ii) The number of hosts per subnet generated inward (i) inward a higher house

(iii) With the assistance of a table, listing the subnets, first, end too broadcast IPs inward each subnet.



/10=255.192.0.0



Answers:

(i) Number of subnets =2^x where x equals the number of bits borrowed. If the default subnetmask for degree Influenza A virus subtype H5N1 is /8 which is 255.0.0.0 too nosotros are given /10 inward this question, it hence agency nosotros borrowed ii bits. Substituting ii into the formula, nosotros convey 2^2=4. We convey 4 subnets.

(ii) Number of hosts per subnets=2^y-2, where y equals the number of off bits. To teach our off flake is simple. 32-10=22. IPv4 is a 32-bit address but nosotros are hand /10 inward this question, therefore, nosotros merely subtract ten from 32 to teach 22. Now substituting 22 into the formula, nosotros teach 2^22-2=4,194,302. nosotros volition convey 4,194,302 per each of the 4 subnets.

(iii)We demand the block size to live able to listing out subnets. Block size is 256-192=64. Because the subnet flake falls inward the mo octet, nosotros volition listing our subnets amongst the alter happening inward the mo octet.

Example 2: Given 10.0.0.0/17, create upwards one's heed the following:

(i) The number of subnets that the given IP too subnetmask volition produce
(ii) The number of hosts per subnet generated inward (i) above
(iii) With the assistance of a table, listing the subnets, first, end too broadcast IPs inward each subnet.

/17=255.255.128.0

Answers:
(i) Number of subnets=2^9=512
(ii) Number of hosts per subnet=2^15-2=32,766
