I can't reproduce it here (tried your exact sequence):

[23:21:21] *** Looking up 210.193.16.22
[23:21:22] *** Looking up 210.193.16.23
[23:21:22] *** Looking up 210.193.16.24
[23:21:37] *** Unable to resolve 210.193.16.22
[23:21:37] *** Looking up 210.193.16.25
[23:21:42] *** Unable to resolve 210.193.16.23
[23:21:48] *** Unable to resolve 210.193.16.24
[23:21:54] *** Unable to resolve 210.193.16.25

Also tried resolving >15 ips and still no crash,
tested both mIRC 6.01 and 6.03 at w2k prof. SP3, dnsapi.dll 5.00.2195.6012.
