check_host_alive warns for wrong IP

Hi all,
I think check_host_alive has got sth wrong with it.

I have controlled output of "check_host_alive" when I saw my host down. It
was saying: (on page nagios/cgi-bin/extinfo.cgi? bla bla for host detail)
CRITICAL - Host Unreachable (85.29.1.77)

However the fact is that I have grepped all relevant nagios configuration
files and never seen an IP like "85.29.1.77", I just defined host with IP
.26.77. On the other hand, I tried to run it on console, expectedly it said:
CRITICAL - Host Unreachable (85.29.26.77)

Any ideas?

By the way,
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt
Iface
85.29.1.64      0.0.0.0         255.255.255.192 U         0 0          0
eth0
0.0.0.0         85.29.1.100     0.0.0.0         UG        0 0          0
eth0


Regards,
Dinçer
