Both Cisco and Juniper use the standardized documentation IP ranges in their example/lab configurations and training materials.

Cisco did recommend to use 1.1.1.1 (or did default to? commentary online is unclear), but in a different space: for the DHCP server with DHCP proxying in their WLAN products. They might be referring to that.

I have been going through Cisco Netacad materials for last 2 years and I've seen 1.1.1.1 in examples. Though I just did a search and did not see 1.1.1.1 mentioned anymore.
