[Cialug] Another Google issue

[L. V. Lammert]

Given this SPF:

;; ANSWER SECTION:
omnitec.net.		3600	IN	TXT	"v=spf1
ip4:206.197.251.199 ip4:206.197.251.200 ip4:206.197.251.201
ip4:206.197.251.202 ip4:206.197.251.198 ip4:107.152.37.23
include:_spf.google.com -all"

Why does Google not validate .202?
