mask. I'm trying to use a /18
mask for my 3 large subnets, and a /21
mask for my 6 smaller subnets. But VPC creation fails because it cannot come up with non-overlapping subnets. Am I missing something, or is this maybe a gap in the awsx VPC computation? the /18
mask gives me 4 prefixes that I can assign to the 3 subnets, leaving one prefix I can give to the 6 smaller subnets. /21
should give me 8 subnets using the remaining prefix.billowy-army-68599

10.0.64.0/18
10.0.128.0/18
10.0.192.0/18
And then you’d like to take one of these four prefixes (I’ll use the last one) and subdivide it into eight smaller subnets:
10.0.192.0/21
10.0.200.0/21
10.0.208.0/21
… (omitting for brevity)
10.0.248.0/21
Is that right?brief-church-51632
