HI,
what is correct answer and why for this test:
Which IP address range is allowable given an IP address 172.37.2.56 and
a) 172.37.2.48 to 172.37.2.63 b) 172.37.2.48 to 172.37.2.62 c) 172.37.2.49 to 172.37.2.62 d) 172.37.2.49 to 172.37.2.63 e) 172.37.2.55 to 172.37.2.126
Thx

172.37.2.56 - class B address - means /16 16+12 =3D 28 so mask is 255.255.255.240Answer c) subnet 172.37.2.48 broadcast 172.37.2.63 usable addresses: 172.37.2.49 - 172.37.2.62
Hope it's cler now

Are you sure 12-bit subnetting ?
correct
I thinked the subnet was 255.240.0.0 and not 255.255.255.240.
Thx very much db
Sorry for worming into this thread, but now I have a question ...
It's easy to see that the useable address range is answer C (172.37.2.49 to
172.37.2.62) but the subnet range is shown by answer A (172.37.2.48 to 172.37.2.63). I'm assuming it is the wording that determined the correct response.Is it normal for the tests to differentiate between a subnet range and an IP address range by these terms? My biggest problem with these things is getting stung by the wording. Thanks for any response given.

subnet range and ip address range are similar. Every IP is in a subnet. But this question only asked for IP ragnes within a particular subnet. And the answers only involved that. The Q didn't say FSLM or VLSM, though i think it makes no diff. It just asks about that subnet.
If it were FLSM then you get a range of subnets which you could list. You would specify them with an IP and a mask, like the question gave. Or you coudl list each individual one. They won't go up in increments, I don't think an "a.b.c.d - e.f.g.h" range is suitable
To cut a long story short. The Q asked for IP range. The Ans were clearly all ok as IP Ranges. I wouldn't even think of interpreting them as subnet ranges.
C is usable IP range. A is possible IP range.
the ranges are prob distinguished by terms like usable vs possible. usable being restricted. possible being all subnets allowed.
