weird spider/bot activity?

[erickoh]

Hi,

I was going through my log when I saw these lines

212.87.60.78 [13:13:09] "HEAD /m.htm HTTP/1.0" 200 0 "Mozilla/3.01 ( compatible; MSIE 5.01; Windows 95; ezn IE )"
212.87.60.78 [13:13:11] "HEAD /m.htm HTTP/1.0" 200 0 "Mozilla/4.73 ( compatible; MSIE 4.01; AOL 5.0; DigiExt )"
212.87.60.78 [13:13:11] "HEAD /m.htm HTTP/1.0" 200 0 "Mozilla/4.0 ( compatible; MSIE 5.5; Windows NT4.0; DigiExt )"

repeat about 1100 times with varying user agents

212.87.60.78 [13:14:44] "HEAD /m.htm HTTP/1.0" 200 0 "Mozilla/4.72 ( compatible; [en]; Windows NT4.0; DigiExt )"

and another one (2 days later)

210.220.153.82 [21:06:24] "GET /b/index.htm HTTP/1.0" 200 11403 "Mozilla/3.0 (compatible)"
210.220.153.82 [21:06:32] "HEAD /b/index.htm HTTP/1.0" 200 0 "Mozilla/3.0 (compatible)"
210.220.153.82 [21:06:33] "HEAD /b/index.htm HTTP/1.0" 200 0 "Mozilla/3.0 (compatible)"

repeat 7720 times

210.220.153.82 [21:14:54] "HEAD /b/index.htm HTTP/1.0" 200 0 "Mozilla/3.0 (compatible)"

[rests for a minute, then...]

210.220.153.82 [21:16:08] "GET /b/index.htm HTTP/1.0" 200 11403 "Mozilla/3.0 (compatible)"
210.220.153.82 [21:16:13] "HEAD /b/index.htm HTTP/1.0" 200 0 "Mozilla/4.0 (compatible; MSIE 5.0; Win32)"
210.220.153.82 [21:16:13] "HEAD /b/index.htm HTTP/1.0" 200 0 "Mozilla/4.0 (compatible; MSIE 5.0; Win32)"

repeat 11390 times

210.220.153.82 [21:27:57] "HEAD /b/index.htm HTTP/1.0" 200 0 "Mozilla/4.0 (compatible; MSIE 5.0; Win32)"

I'm a newbie webmaster, so I'm not sure what to do or feel about this. Could it just be a bot with faulty algorithm?
Does this kind of thing happen all the time and should I take some action?

Thanks in advance!

Hi erickoh - welcome to WebmasterWorld.

That IP is part of the Korea Network Information Center. Their whois is here: [whois.nic.or.kr...] - I don't know Korean and I didn't have my Windows disc to install the language pack so that's where the trail ended for me ;)
