supernet() works

Code
  supernet(ip_network("0.0.0.0/0"))
Condition
  Error in `supernet()`:
  ! `x` must have a supernetwork
Code
  supernet(ip_network("::/0"))
Condition
  Error in `supernet()`:
  ! `x` must have a supernetwork

subnets() works

Code
  subnets(ip_network("0.0.0.0/32"))
Condition
  Error in `subnets()`:
  ! `x` must have a subnetwork
Code
  subnets(ip_network("::/128"))
Condition
  Error in `subnets()`:
  ! `x` must have a subnetwork

missing values work

Code
  supernet(ip_network("192.168.0.0/24"), new_prefix = NA)
Condition
  Error in `supernet()`:
  ! `new_prefix` must be a integer vector

Code
  subnets(ip_network("192.168.0.0/24"), new_prefix = NA)
Condition
  Error in `subnets()`:
  ! `new_prefix` must be a integer vector

input validation

Code
  supernet(ip_address("1.2.3.4"))
Condition
  Error in `supernet()`:
  ! `x` must be an <ip_network> vector
Code
  supernet(ip_network("192.168.0.0/20"), new_prefix = "yes")
Condition
  Error in `supernet()`:
  ! `new_prefix` must be a integer vector
Code
  supernet(ip_network("192.168.0.0/20"), new_prefix = -1L)
Condition
  Error in `supernet()`:
  ! `new_prefix` must be positive
Code
  supernet(ip_network("192.168.0.0/20"), new_prefix = 21L)
Condition
  Error in `supernet()`:
  ! `new_prefix` must be less than `prefix_length(x)`

Code
  subnets(ip_address("1.2.3.4"))
Condition
  Error in `subnets()`:
  ! `x` must be an <ip_network> vector
Code

Condition
  Error in `subnets()`:

Code
