Class: RuboCop::Cop::Style::IpAddresses
- Includes:
- RuboCop::Cop::StringHelp
- Defined in:
- lib/rubocop/cop/style/ip_addresses.rb
Overview
This cop checks for hardcoded IP addresses, which can make code brittle. IP addresses are likely to need to be changed when code is deployed to a different server or environment, which may break a deployment if forgotten. Prefer setting IP addresses in ENV or other configuration.
Constant Summary collapse
- IPV6_MAX_SIZE =
IPv4-mapped IPv6 is the longest

- MSG =
'Do not hardcode IP addresses.'
