It would be /23 or 255.255.254.0.

That WILL work for your two networks here, but won't always work. For
example if you wanted to get 172.29.101.0 and ..102.0 together, then it
won't work because 100 pairs with 101 and 102 pairs with 103.

In that case you could use /22 or 255.255.252.0 but that would combine
172.29.100.0 through 172.29.103.0 for a total of 1024 addresses.

I seem to have a mind block. I need the correct netmask/cidr for two
networks to combine.
172.29.100.x
172.29.101.x

I'm using /22 (255.255.252.0) but that does not seem to be correct.

Thoughts?
