nwdiag
nwdiag has been created by Takeshi Komiya and allows to quickly draw network diagrams. So we thank him for his creation! Since the syntax is clear and simple, this has been integrated within PlantUML. We reuse here the examples that Takeshi has documented.
Simple diagram
@startuml
nwdiag {
network dmz {
address = "210.x.x.x/24"
web01 [address = "210.x.x.1"];
web02 [address = "210.x.x.2"];
}
network internal {
address = "172.x.x.x/24";
web01 [address = "172.x.x.1"];
web02 [address = "172.x.x.2"];
db01;
db02;
}
}
@enduml
define multiple addresses
@startuml
nwdiag {
network dmz {
address = "210.x.x.x/24"
// set multiple addresses (using comma)
web01 [address = "210.x.x.1, 210.x.x.20"];
web02 [address = "210.x.x.2"];
}
network internal {
address = "172.x.x.x/24";
web01 [address = "172.x.x.1"];
web02 [address = "172.x.x.2"];
db01;
db02;
}
}
@enduml
grouping nodes
Not fully implemented yet
@startuml
nwdiag {
network Sample_front {
address = "192.168.10.0/24";
// define group
group web {
web01 [address = ".1"];
web02 [address = ".2"];
}
}
network Sample_back {
address = "192.168.20.0/24";
web01 [address = ".1"];
web02 [address = ".2"];
db01 [address = ".101"];
db02 [address = ".102"];
// define network using defined nodes
group db {
db01;
db02;
}
}
}
@enduml
@startuml
nwdiag {
// define group at outside network definitions
group {
color = "#FF7777";
web01;
web02;
db01;
}
network dmz {
web01;
web02;
}
network internal {

Extended Syntax
@startuml
nwdiag {
network Sample_front {
address = "192.168.10.0/24"
color = "red"
// define group

web02 [address = ".2"]
}
}
network Sample_back {
address = "192.168.20.0/24"
web01 [address = ".1"]
web02 [address = ".2"]
db01 [address = ".101", shape = database ]
db02 [address = ".102"]
// define network using defined nodes
group db {
db01;
db02;
}
}
}
