When is an anycast ip an anycast ip ?

that’s a question i was asked recently. As LTNN (Long Term Networking Nerd), i’m aware of Unicast, Multicast, Broadcast and also Anycast. so, let’s have a look into this.

hint: this article is not about how to setup your own anycast network. this may follow soon ?!?

Terminologie

Unicast 1:1

Sending a message from one sender to one recipient

Multicast 1:many

Sending a message from one sender to multiple recipients

Show Hostvars

ansible -m debug -a "var=hostvars['puffy']" localhost

Build Encrypted Variable

echo -n 'letmein' | ansible-vault encrypt_string --stdin-name 'vault_my_var'
vault_my_var: !vault |
