I apologize for that.
My previous post about 10.10.x.x is just an example.
Please disregards 10.10.x.x range as it is only an example.
The correct range for a 255.255.252.0 subnet mask is
10.2.4.0 - 10.2.7.255
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
*.*.*.27 0.0.0.0 255.255.255.255 UH 0 0 0 venet0
10.2.5.2 0.0.0.0 255.255.255.255 UH 0 0 0 venet0
*.*.*.240 0.0.0.0 255.255.255.255 UH 0 0 0 venet0
*.*.*.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.2.4.0 0.0.0.0 255.255.252.0 U 0 0 0 eth1
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
0.0.0.0 *.*.*.1 0.0.0.0 UG 0 0 0 eth0
note: *.*.* = is a public subnet.
