The netmask really sticks out here, 244 wouldn't be a valid netmask in most
cases... I haven't tested, but my guess would be that its really being
rejected and a standard class C mask is being used.
Here is a quick list for reference:
255.255.255.255 (32bit, used for routing statements, not usually valid for a
host)
255.255.255.254 (31bit, usually not valid for a host)
255.255.255.252 (30bit)
255.255.255.248 (29bit)
255.255.255.240 (28bit)
255.255.255.224 (27bit)
255.255.255.192 (26bit)
255.255.255.128 (25bit)
255.255.255.0 (24bit, sometimes reffered to as a class C mask)
