Hi, I've been a new Verizon residential FIOS user since May and the mysterious connectivity issues at home lead me to a bit of hunting. From what I can tell, the Verizon network as a whole effectively blocks or filters following major networks. The same networks are mostly reachable from AT&T LTE networks and major cloud computing providers. Below is a comparison of 'show ip route' of a VZ router and a routeviews router. <VZ INET router># 81.0.0.0/8 is variably subnetted, 2835 subnets, 14 masks 121.51.0.0/16 <empty> 182.254.0.0/16 is variably subnetted, 3 subnets, 2 masks route-views.routeviews.org> 81.0.0.0/8 is variably subnetted, 3247 subnets, 19 masks 121.0.0.0/8 is variably subnetted, 2571 subnets, 18 masks 182.254.0.0/16 is variably subnetted, 113 subnets, 5 masks Anyone able to validate my findings, and/or take this issue to higher VZ support? Thanks.
