*.home.gateway timedout - Odd DNS Client Events (Event Viewer) warnings

Question

I have noticed DNS Client Events warnings in my Event Viewer when my computer is woken from sleep. I have supplied the differing data below and a sample event detail below that.

mail.google.com (valid)
wpad.home.gateway (valid)
wwbqyypbrv.home.gateway 
woxdqqronl.home.gateway 
ibadvkibbx.home.gateway 
pxrzmscxdz.home.gateway 
oqmjtajejg.home.gateway 

home.gateway is listed in my router as the Device Host Name. My router is a Billion BiPAC 7300N.

Apart from it being a warning about accessing those addresses and that some of the names are odd; should I be concerned? thank you.

(I had difficulty determining tags for this. Pls edit if you can improve)

There is no such thing as "a wpad". That lookup results from your WWW browser attempting WWW proxy auto discovery (WPAD). That's a serious security hole when one doesn't actually have WPAD locally and you should turn that mechanism in your WWW browser off.

That your system regularly polls a mailbox for new mail is probably a much lesser concern. ☺
