strange queries incrementing letter by letter

[Kevin Kretz]

I see occasional series of queries like this, from within my network and among disparate types of host (linux, windows): 

If there's a host called 

hostname.mynet.com 

I'll see a sequence of queries like 

hostname.m 
hostname.my 
hostname.myn 
hostname.myne 
hostname.mynet 
hostname.mynet.c 
hostname.mynet.co 
hostname.mynet.com 

Can anyone tell me what this is? 


thanks 

Kevin
