Who are these referring domains?

Seeing lots of traffic from them

[androidtech]

I've been going over my logs and I'm getting a lot of traffic from some strange domains. The ones I'm most interested in are:

page-not-found-dot-net
mywebsearch-dot-com
quickbrowsersearch-dot-com
dropspam-dot-com
qsrch-dot-com

There's also some coming from a domain that starts with the number 17, followed by different numbers after a period.

I'm assuming they are alternative search engines. Does anybody have any information on these?

My experience from most of those you listed are that they are Spyware based search engines. Those search engines have spyware that they include on other sites, software etc and the spyware is then installed onto the unaware users computer. The spyware then redirects the users computer to the said search engine or alternatively when the user searches using google, yahoo, MSN ( real search engines )etc the proper results are diluted by paid search results from the spywares search engine.

myway.com uses mywebsearch.com domain for search result.
