2 New User Agents

New to me, and a bit of background on them...

[Eric_Lander]

Hey all. I recently started a new site and found a few new spiders / bots coming in. And, I wanted to offer as much information as I could on them - and hopefully leave room for you all to chime in with some more information.

Anyways, here is the list.

Sqworm/2.9.85-BETA (beta_release; 20011115-775; i686-pc-linux-gnu) 
Pizilla++ ver 2.45

I know, it's only two user agents, but I wanted to find more about them. Here is what I know.

Sqworm/2.9.85-BETA
This was mentioned in a previous thread... [webmasterworld.com]
It may be just another browser, or perhaps an application for offline viewing - but it came through and requested 32 pages on my site last week. On other domains, I have only see it make one request.

After searching on some engines for "Sqworm" I've found out just two things. A LOT of people leave their web site stats wide open to the public, and, there is a game called "Sqworm" available at CNETAsia.

But, I have nothing to go by as to what this is all about, or what it is doing. I'm not all that worried though - as I am inclined to believe it is just another browser. Anyone else have information?

Pizilla++ ver 2.45
Pizilla came in and requested 14 pages, so again, I'm immediatly inclined to believe that it is a browser. A look at a cheat sheet [psychedelix.com] of IP/UA listings confirmed this.

It is described as "Private user-agent via Hurricane Electric Internet Services" - and they seem to be just another ISP. Can anyone clarify if this UA is for their own browser, or for another purpose?

I've heard rumors that 'net backbone providers may send out US's like this to ensure that DNS entries within their servers are legitimate... But, doubt that is the case.

Thanks,
- Eric Lander
