Why would a Facebook device be sending Spi packets at home user ?

["Mr. James W. Laferriere" <babydr () baby-dragons com>]

        Hello All ,
        Maybe I am missing (or have missed) something .

        Here is the log entry & dig & whois info .  Just kinda interested in info on this phenomenon .

	I've received many SPI assoc. requests at my poor ol' router over the 
few years it's been online ,  Most of them are from S.E. Asia & few from Africa 
others from EU ,  But by & far most of them are USA based Webservers by their 
dig & whois info .  A very small few are from org's such as FB .  I usually just 
ignore these as some fluke or if I know a contact at the site I send them the 
info .

 1 )    Is there an orginazation that is mapping unsecured ipsec boxen ?
 2 )    Has or is anyone else receiving attempts at establishing association ?
 3 )    Is anyone recording these or interested in keeping records ?
 4 )	Anything elso I would be interested in along the lines of assoc. 
attempts & why they are being attempted ?

                Tia ,  JimL
