resolvehost

Resolve network host name or IP address

Syntax

name = resolvehost(host)

name = resolvehost(host,"name")

address = resolvehost(host,"address")

[name,address] = resolvehost(host)

Description

name = resolvehost(host) and name = resolvehost(host,"name") return the name of the specified host, where host is the network name or IP address.

address = resolvehost(host,"address") returns the address of the specified host.

[name,address] = resolvehost(host) returns both the name and address of the specified host.

Examples

Identify Network Name from Host Address

Provide an IP address to view the associated host name.

name = resolvehost("144.212.244.17")

name = 
'www-ahprod.mathworks.com'

You can specify the optional input argument "name" as well.

name = resolvehost("144.212.244.17","name")

name = 
'www-ahprod.mathworks.com'

Specifying the host name instead returns the same host name.

name = resolvehost("www.mathworks.com")

name = 
'www.mathworks.com'

Resolve IP Address from Host Name

Provide a network host name to view the associated IP address. You must include the input argument "address".

address = resolvehost("en.wikipedia.org","address")

address = 
'208.80.154.224'

Specifying the IP address instead returns the same IP address.

address = resolvehost("208.80.154.224","address")

address = 
'208.80.154.224'

Resolve Network Name and IP Address from Host

You can view both the network name and IP address of a specified host. You can specify either the name or IP address. In this example, the resolvehost function returns the name and address from the provided host name.

[name,address] = resolvehost("en.wikipedia.org")

name = 
'en.wikipedia.org'

address = 
'208.80.154.224'

You can also specify the IP address instead.

[name,address] = resolvehost("208.80.154.224")

name = 
'text-lb.eqiad.wikimedia.org'

address = 
'208.80.154.224'
