New ISP - With Static IPs... Can anyone tell me subnet mask?

[BackCat3]

Hello,

 

I've just switched internet providers and the new one has assigned me 4 static ip addresses, can anyone tell me the subnet mask to use for them?

 

 

96.25.99.224 - I intend to use this for the router.

96.25.99.225 - Server #1

96.25.99.226 - Server #2

96.25.99.227 - Server #3

 

These subnet masks are confusing as hell :\

255.255.255.248?

255.255.255.248?

 

Thats my guess, I just wanted to make sure.

Surely the new ISP is the best place to get this? It could be 255.255.255.0, 255.255.0.0, 255.0.0.0 etc - drop them an email and surely they'll clarify it for you?

Those precise IPs are a /30 (255.255.255.252). I used GeekTools Aggis Interface to check this out.

 

I thought that the command line aggis tool allowed you to input a range (e.g. 96.25.99.224 - 96.25.99.227), but I can't see how to do this on the Geektools web page. Nor can I find the source code for aggis.c - it's always been elusive.

 

Warning: it used to be that only two addresses in a /30 were usable, but that generally isn't the case now.

They are 255.255.255.252 (manual calculation)

 

Av awful ip range as your DHCP scope will have to be limited.

if it is 252 (correct me if im wrong) you cannot use 96.25.99.224 because it will be your network address and you cannot use 96.25.99.227 as it will be your brodcast address what leaves you with only 2 usable addresses and if its 248 you should get 6 usable addresses instead of 4

but still you are better off giving them a call im sure thats the way it works on lan's not sure about isp

[BackCat3]

They replied simply telling me the subnet was 255.255.255.0

[p3dr0]

cant argue with that

[BackCat3]

After trying to get it to work for a good 2 hours turned out they gave me an IP address a digit off.... :\

[featured_spectre]

LMAO. Thought it was too good to be true for the IP range.

 

Perhaps just have the router set to one of those IPs, and do everything else to your own IP scheme in future?

I wanted them to go with BT Bussiness, as I've got a few companies using them never had any problems... They decided upon some company no one has ever heard of that resell of TalkTalk... Download Speed: 0.18meg :\

In future I'm sticking with one IP and just smartly port forwarding.
