Ronen,
Why do you need to probe the networks? Just to get some traffic flowing to satisfy your curiosity? If you find out that some gateways are up, and some not, how is this information helpful to you since they are not under your control, you can not do anything about it, and you will probably not access them anyway since they don't offer any services you need.
A lot of users consider any probing not acceptable and consider even some 2-3 pings per hour excessive, and any unnecessary traffic is not welcomed.
By the way, there is no 44 gateway address defined for subnets, so you will probably will not get responses because you can not guess them and not everyone uses the first or last IP of the subnet as the gateway IP. To ping the public gateway address will not do either, since a lot of them do not respond to icmp requests.
And as described, let's assume everyone starts doing this. Having 500 subnets probing your network every 5 minutes will give some 1Mb traffic per request set (3 pings, 60 bytes each, 10bits/byte because of overhead). On a 1200bps radio link this will saturate the link...
So probe the ones interesting to you, in agreement with the other sysop. If they accept, it is ok, If not, don't.
