There may be a problem with Centaury browser.

I recently noticed that every time I do a Google search with Centaury, I get something like this:
http://www.google.com/#spf=1605563882969
....each time I go to Google the last six numbers change.

With Mypal and Firefox the address is this:
https://www.google.com/?gws_rd=ssl (Mypal)
https://www.google.com/?gws_rd=ssl (Firefox)
....and remains consistent each time I go to Google.

A brief search turned up these links:
https://support.google.com/a/answer/33786?hl=en
https://support.google.com/a/answer/35232
https://support.google.com/a/answer/48323
https://docs.mailshake.com/article/221-dns-record-google

The thing is I never signed up for a domain account, or set up SPF, so unless this is something my ISP has done, it looks pretty dang shady to me, and I suspect the above links are not telling the whole story. I suspect this could be another way for Google to link searches to IP address. Either way, it seems to be tied exclusively to Centaury, as the #spf= is MIA in Mypal & Firefox.
