Cybersmart DHCP - IP assignment after cap

[Cadavre777]

This morning I was woken up to people moaning and whining they couldn't browse sites hosted internationally. O, so I can deal with that. Just reconnect and check the routes. This is what I found when working on the gateway:

bash-2.05b# ifconfig pppoe0
pppoe0: flags=8851<UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST> mtu 1492
inet 10.206.21.29 -> 10.206.21.1 netmask 0xff000000
inet6 fe80::201:2ff:fe42:24f1%pppoe0 -> prefixlen 64 scopeid 0x20



I would expect this from some cheap nasty little WISP but not a SAIX reseller. I have stopped laughing, because it' not funny now that I cant carry on with my work

hmm wish I knew what all that meant...

It means they have given me an IP address thats supposed to be for private networks, a LAN

The private IP addresses that you assign for a private network (inter-office LAN, Internet Service Provider customer bases, campus networks, etc) should fall within the following three blocks of the IP address space:

10.0.0.1 to 10.255.255.255, which provides a single Class A network of addresses, which would use subnet mask 255.0.0.0.
(theoretically up to 16,777,215 addresses, good for VERY large enterprises like internet service providers or other global deployment)

172.16.0.1 to 172.31.255.254, which provides 16 contiguous Class B network addresses, which would use subnet mask 255.255.0.0.
(theoretically up to 1,048,576 addresses, good for large enterprises like colleges and governmental organizations)

192.168.0.1 to 192.168.255.254, which provides up to 2^16 Class C network addresses, which would use subnet mask 255.255.255.0.
(theoretically up to 65,536 addresses, widely used by default in consumer/retail networking equipment)

Explanation of Subnet masks, Network classes, and other technical info is readily available on the internet.

Hope that explains a bit more.

Some WISPS use the 10.x.x.x range, and it's a PITA in getting an public IP in such a case.

It seems someone on the network downloaded over 500 mb in one day getting us capped. So it wasn't unintentional that they assign private IP's to capped users, but to allow them to top up after reaching the cap. Before you were assigned an IP from SAIX's ranges, but could only browse Cybersmarts site.
