## check whether IPv4 ranges are valid

### Description

`validate_range` checks whether a vector of IPv4 CIDR ranges ("127.0.0.1/32") are valid or not.

### Usage

    validate_range(ranges)

### Arguments

`ranges` | a vector of IPv4 ranges

### Value

a logical vector, where TRUE indicates that the provided entry is valid, and FALSE that it is not (or isn't an IP range at all)

### See Also

`ip_classify` for classifying (and, incidentally, validating) IPv4 and IPv6 addresses, or `range_boundaries` for identifying the minimum and maximum IPs within a range.

### Examples

    validate_range("127.0.0.1/32")
    #[1] TRUE
    validate_range("127.0.0.1/33")
    #[1] FALSE
