What to look out for when increasing network size

http://serverfault.com – I'm a programmer by profession and don't understand this stuff all that well, so I apologise if this question is unclear, and I will try to keep improving it. I have a /24 IPv4 network, so approximately 255 IP addresses. Very soon we will have more than 250 devices on the network, and this number will continue to grow over time, therefore I have to expand the network capacity somehow. I am already making heavy use of DHCP to reduce the number of devices using an address at once. I can increase the size of the subnet to a /22, giving ~1024 IP addresses. If I do this, will there be issues with ()

I have been given the following IP 192.168.14.137/25 and asked to divide the network into 2.

This is what I've come up with:

The subnet mask is therefore 255.255.255.128

The network address is 192.168.14.128

There are a total of 128 available addresses (including the network address and broadcast address)

To divide the network we create to subnets:

192.168.14.128/26

192.168.14.192/26

Find mobile device on network 17 weeks 2 days ago

I'm trying to write a small program that will poll the network for certian ip addresses or mac addresses (though mac doesnt seem to show up past my WAP)

My networking isn't very strong but many mobile devices don't support ping on the network (im looking at you iphone)

is there a fairly easily to poll all network addresses on the network regardless if they will reply to ping?

We have a small office network with DSL and a Netgear WNR-2000 wireless router acting as a DHCP server. There are nine devices connected to the router, wirelessly and wired. Whenever a Mac computer tries to connect, it's unsuccessful until we restart the router.

Hi my setup is through network manager and have configured my WAN connection to DHCP and my LAN connection to 'shared to other computers'. It all works except I need my ip addresses on the clients to be on the 192.168.x.x range not the 10.42.0.x subnet. Anyway i can configure network manager to give out addresses on the 192.168.x.x subnet??

Thanks

This is very basic question but i really could not find how it will be.There are two network IP address are given 10.0.0.10/24, 30.0.0.10/24 .Would like to know are these two addresses in same network or in different networks

I believe its in same network but one of tutorials says its in different network may be I interpreted wrong.

Can anyone please give clear picture about IP address ?

Hy there,

I was wondering if it is possible to have two different networks connected on one router who which have the same ip, and are differentiated by a subnet mask?

For example:

192.168.1.0/24 192.168.1.0/16

Are they considered different because their network prefix is different?

Does that mean that with the ip address 192.168.1.0 we can actually address.

192.168.1.0/31 -> 2 computers - 2

I have a network of about 90 PCs and about 25 network printers. In near future i will promote one server to DC. However, now PCs on my network have static IP addresses.

It is a real mess now with IP addresses. Printers are not statically assigned to on range for ex 192.168.1.50-75.

I manage a reasonably small network (150 machines or so).
