DHCP

The dhcp command configures the network automatically:

> dhcp -v
DEBUG: DHCP Discover transmitted
DEBUG: DHCP Offer received
ip:  10.0.2.15/24
gw:  10.0.2.2
dns: 10.0.2.3

HOST

The host command performs DNS lookups:

> host example.com                                                                                 
example.com has address 93.184.216.34

TCP

The tcp command connects to TCP sockets:

> tcp time.nist.gov 13
Connecting to 129.6.15.30:13

58884 20-02-05 19:19:42 00 0 0  49.2 UTC(NIST) *

This could also be done with the read command:

> read /net/tcp/time.nist.gov:13
Connecting to 129.6.15.30:13

58884 20-02-05 19:19:55 00 0 0  49.2 UTC(NIST) *

HTTP

Requesting a resource on a host:

> http example.com /articles/index.html

Is equivalent to:

> read /net/http/example.com/articles

And:

> read /net/http/example.com:80/articles/index.html
