[Verse 1]
Your message starts a journey, broken into tiny pieces
Every packet gets a number, like breadcrumbs for releases
Layer four wraps layer three, like envelopes inside
TCP makes sure they all arrive, none get left behind
[Chorus]
TCP connects, IP directs, packets dancing through the wire
Transmission Control Protocol keeps the data flowing higher
Internet Protocol routes the way, addressing every node
Remember TCP-IP, that's how the internet's code flows
[Verse 2]
Handshakes happen first you see, synchronize the connection
Three-way greeting sets the stage for perfect packet protection
SYN and ACK and SYN-ACK too, like knocking on a door
Before the real conversation starts, we shake hands once more
[Chorus]
TCP connects, IP directs, packets dancing through the wire
Transmission Control Protocol keeps the data flowing higher
Internet Protocol routes the way, addressing every node
Remember TCP-IP, that's how the internet's code flows
[Bridge]
But numbers are so hard to remember
One-nine-two dot something dot whatever
So DNS translates the names we type
Google dot com becomes an IP sight
Recursive queries climb the tree
Root servers hold the master key
[Verse 3]
Domain Name System breaks it down, like phone books in the cloud
Dot com and dot org and dot net, each hierarchy's proud
Your browser asks the resolver, "Where does Facebook live?"
The answer comes back lightning fast, the address servers give
[Chorus]
TCP connects, IP directs, packets dancing through the wire
DNS translates the names we type to addresses that inspire
Internet Protocol routes the way, addressing every node
Remember TCP-IP-DNS, that's how the internet's code flows
[Outro]
From typing in a website name
To packets reaching their destination
TCP-IP and DNS together
Power our connected nation
