    So you lost a connection, and something is out of state..  10.20.45.128 was talking to 173.194.65.95 on https, which is not a reverse resolve with dns.. Your just over the little icon that would do that for you for that IP ;)

    ;; OPT PSEUDOSECTION:                                               
    ; EDNS: version: 0, flags:; udp: 4096                               
    ;; QUESTION SECTION:                                                 
    ;95.65.194.173.in-addr.arpa.    IN      PTR

    ;; ANSWER SECTION:                                                   
    95.65.194.173.in-addr.arpa. 86400 IN    PTR    ee-in-f95.1e100.net.

    That is Google..

    NetRange:      173.194.0.0 - 173.194.255.255
    CIDR:          173.194.0.0/16
    OriginAS:      AS15169
    NetName:        GOOGLE
    OrgName:        Google Inc.
    OrgId:          GOGL

    These sorts of entries in the log will happen all the time..
