Our office network runs on
10.213.1.1/24
so all addresses in 10.212 and 10.213 should be local.
As Jerry mentioned, this is not correct. 10.212 and 10.213 are on different subnets if your mask is 24 bits in size:
10.212 = 0b00001010.0b11010100 10.213 = 0b00001010.0b11010101
As you can see, they only have 15 bits in common, so for them to be in the same subnet (no routing required) your network would have to be 10.212.0.0/15 at the minimum.
and I have a TFTP server on 10.213.1.105
if I set my office pc to 10.212.0.99 I can ping 10.213.1.105
If this is so and the netmask listed above is correct, there's probably a router on 10.212. Running traceroute will tell you for sure.
so far so good
if I set u-boot up so the printenv at power-on looks like
ethaddr=00:90:46:20:000:99 eth1addr=00:90:46:20:100:99 ipaddr=10.212.000.99 serverip=10.213.1.105 gatewayip=10.213.1.1
Try setting this to 10.212.1.1 and see what happens.
netmask=255.254.0.0 bootfile=99/uImage ethact=macb1
then if I do
ping 10.213.1.105
it fails.
but after setting
setenv ipaddr 10.213.0.99
No surprise.
it works
Can anyone suggest why?
