Question

Computer communications

4.a (8 points) a A large number of consecutive IP addresses are available starting at 198.16.0.0. Suppose that four organizations, A, B, C, and D, request 512, 2000, 1000, and 4000 addresses, respectively, and in that order. For each of these, give the first IP address assigned, the last IP address assigned, and the mask in the w.x.y.z/s notation.

Answer 1

» Sina the no. 10. of bits assigned for Network ID, IS NOT given , so this the case of classful IP Address is dressing. Now, sina the address is 198.16.0.0, So in which Also, sinu jt's the entire a it belongs to Class e first 3 byte supusent the Network Id. claseful addressing network will be assigned even if the organization asking fost less no. of networks. already know 1 network in class c 28 hosts laddrusses = 25-6 addruises ون sou we that will be having For Org. А first add. 198.16.0.0 Last add = 198.16 1.255 Mark 255.255.255.0 Reason: so > the bits of host 10 are It nuds 512 (256*2) addresses 2 kw will be assigned. Last add when all set to I first add when all bits of first who are assigned as o " for org. B Sinu üst suquim 2000 add., so total 8 nitwoorks wil be given. So, 198.16.2.0 first add Last add 198.16.9.25-5- . Mask 288.285.255.0 for org Sinu it huds looo add 30 , total 4 (256*4=1024) ) networks will be given first add 198.16.10.0 = 198.16.13.25-5- Last add Mark 255 255.255.0 for org D Since it nude 4000 add, so total 16 (256*16=4096) Metworks will be giren . So first add 198.16.14.0 Last add 198.16. 29.255 255.255.255.0 Mask A mask in class c is 255.255.255.0 as sit to 1 Nethosk all bits of ale Scanned with CamScanner
