My network admin is out on vacation this week, so I can't get the answer from him. My office's network shares its bandwidth between its phones and its computers. The phones have IPs like 10.22.0.*
where the computers have IPs like 10.100.10.*
. The phones have a web interface that I wish to get access to.
From doing some reading, it looks like I might have to change my subnet mask to get to the web interface. Currently my subnet mask is 255.255.255.0
. From reading What are the essentials of a Subnet mask? I found the following of interest:
So a subnet of 255.255.255.0 means every IP address that matches the first three bytes is your local network, with your given numbers this is anything matching 192.168.001.###. Alternatively a wider subnet of 255.255.0.0 would make your local network 192.168.###.###.
Based on this, I assumed I could change my subnet mask to 255.0.0.0
would let me reach my phone's web interface. My computer's IP was 10.100.10.168
and my phone's IP is 10.22.0.238
. I changed my IP to be 10.100.10.39
and my subnet to 255.0.0.0
. I tried to reach my phone's web interface and was not able to do so.
All of the cat 5e cables in the office drop to the same patch panel which connects to one large switch. The phone works properly, as does my computer. Other phones which have not been configured get a dynamic IP on the 10.100.10.*
network. I'm able to get to the the unconfigured phone web interface without any issues, however they cannot register with the pbx server. The pbx uses asterisk software on linux.
Any ideas on what could be stopping me from reaching my phone's web interface?
