R: Return the hostname associated with particular IP addresses

ip_to_hostname {iptools} | R Documentation

## Return the hostname associated with particular IP addresses

### Description

the opposite, in some ways, of `hostname_to_ip`, `ip_to_hostname` consumes a vector of IP addresses and provides a list of the hostnames that those IPs resolve to. Compatible with both IPv4 and IPv6 addresses.

### Usage

    ip_to_hostname(ip_addresses)

### Arguments

`ip_addresses` | a vector of IP addresses.

### Value

a list, each entry containing a vector of hostnames for the equivalent input IP address (mostly, this will only be one hostname but not always). If the IP cannot be resolved, the list element will be the string "Invalid IP address".

### See Also

`hostname_to_ip`, for the reverse operation.

### Examples

    ## Not run:
    ip_to_hostname("162.243.111.4")
    [[1]]
    [1] "dds.ec"

    ## End(Not run)
