Re: Subnetting questions
If there are 16 hosts then you would have to use the corect subnet. 224 is the same whether it is a routed network or not because a 240 will only support 14 hosts and a 192 will support 62 hosts but that is a waste of space. a 224 will supply 30 addresses plenty for 16 hosts, routers and expansion. The test will see if you know how to subnet it should be clear how many interfaces there are.

Re: Subnetting questions
point less you would have to use a 224 mask so if there is a couple of routers you would have addresses. A 240 would only support 14 hosts. Unless you had 16 routers supporting those 16 hosts then I would recommend a 192. :>) And who is this they Duck - Original Message - From: . <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, October 28, 2000 3:45 AM Subject: Subnetting questions > Hi Friends > > In a subnetting scenario, say for example they say that "Configure the > ethernet network so that it can support 16 hosts." > > Do they mean 16 hosts including all the IP's for the routers in the network, > or does it mean 16 host IP's in addition to the router IP's. > Please let me know > > Thanks > > SV > > _ > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Subnetting questions - off topic
As an offshoot of the original question, among the IP crowd, "host" refers to any device with an IP address. This is different than in the IMB world, where "host" was the mainframe, which "hosted" the applications one accessed via the 32xx terminal on your desk. This terminology spilled over into the Microsoft world in the guise of "host" and "client" terms used in applications like Carbon Copy, where the "host" was the PC that let you control it and the "client" was the PC you were using to call in. I.e. the one PC "hosted" your session. This is not necessarily accurate in terms of origin, but the original sense of the terms "download" and "upload" came out of the IBM world, where one copied things "down" from on high - i.e. the mainframe, and "uploaded" i.e. copied from your lowly connected terminal up to the mighty central machine. The internet was designed around the idea of sharing among equals, which is I suppose why all connected devices became "hosts" (of their own parties?)
