== IP allocation ==

We own the following IP block: 69.55.224.0/20
Which consists of:

<pre>69.55.224.0/24
69.55.225.0/24
69.55.226.0/24
69.55.227.0/24
69.55.228.0/24
69.55.229.0/24 (announced at i2b)
69.55.230.0/24 (internal use and “temp IPs”)
69.55.231.0/24 (announced at i2b)
69.55.232.0/24
69.55.233.0/24 (dedicated customers, internal use)
69.55.234.0/24
69.55.235.0/24
69.55.236.0/24
69.55.237.0/24
69.55.238.0/24
69.55.239.0/24 (“bad boy” block)</pre>

All class C blocks above are subnetted as 255.255.255.0 and have their gateway at .1 (i.e. 69.55.224.12’s gateway is 69.55.224.1)

The exception to this the 233 block which is subnetted up for use by dedicated customers and for some of our internal  (routing) equipment. Here’s how that block is chopped up:

<pre>Range		Mask	Slash	Hosts	Usage
0-127		.128	25	126	dedicated’s (so any customer on this block has a DG of .1 and NM of 255.255.255.128)
128-143	.240	28	14	
144-151	.248	29	6	
152-159	.248	29	6	fw external
160-167	.248	29	6	fw internal
168-183	.240	28	14		
184-191	.248	29	6	
192-223	.224	27	30	nat
224-255	.224	27	30	dedicated’s	DG: 69.55.233.225 (unverified)</pre>
