Red Hat Bugzilla – Bug 3564
ifconfig does not accept very small subnets (such as DSL)
Last modified: 2008-05-01 11:37:50 EDT
I have a DSL service (Covad) which requires me to set the
subnet mask to a subnet having only 5 hosts:
gateway : 18.104.22.168
subnet mask: 22.214.171.124
IP's to use: 152.68.6.<250-254>
Unfortunately Linux does not let me set the subnet mask to
the above value. Solaris and Windows 98 do, and it works
fine on those OS's.
Please try a subnet mask of 255.255.255.248
126.96.36.199 is not a valid subnet mask.
