Why it matters in practice
A prefix can describe one address or a larger range, so reviewers should check the scope before using it in an allowlist or route. IPv4 and IPv6 have different address lengths. Mistyped or overly broad prefixes can allow more sources than intended.
Example
A network engineer checks the prefix length for an IPv4 range before adding that range to a test proxy’s allowlist.
