BSL005 — Using hardcode ip addresses in code

← All rules

Summary

Using hardcode ip addresses in code

Identifiers

Field Value
Rule code BSL005
Compatible alias UsingHardcodeNetworkAddress
Severity WARNING
Enabled by default Yes
Implemented Yes
Tags security, hardware-related

Behavior

  • The public identifier BSL005 and alias UsingHardcodeNetworkAddress are stable.
  • The rule reports the cases documented on this page.
  • Suppressions and project configuration are applied before publication.
  • The rule requires neither an external analyzer nor network access.

Configuration and suppression

BSL### is the primary stable identifier. The compatible alias is accepted in select, ignore, and compatible block suppression comments.

[tool.onec-hbk-bsl]
select = ["BSL005"]
ignore = ["UsingHardcodeNetworkAddress"]

All three suppression families support both a current line and a range. When an opening comment follows code, it affects only that line. Use any one form:

  • noqa:
Value = "example";  // noqa: BSL005
  • bsl-disable:
Value = "example";  // bsl-disable: BSL005
  • compatible BSLLS form:
Value = "example";  // BSLLS:UsingHardcodeNetworkAddress-off

When the same opening comment is on a line by itself, it starts a range. Close it with the matching marker from the same family:

// noqa: BSL005
// code without this diagnostic
// noqa-enable: BSL005

// bsl-disable: BSL005
// code without this diagnostic
// bsl-enable: BSL005

// BSLLS:UsingHardcodeNetworkAddress-off
// code without this diagnostic
// BSLLS:UsingHardcodeNetworkAddress-on

To disable the rule until the end of the file, omit the closing noqa-enable, bsl-enable, or BSLLS:…-on marker.

Opening and closing markers must belong to the same family.

Description

It's forbidden to store in code:

  • Network addresses (ip6, ip4)

There are several ways to properly store such information:

  • Store in Constants.
  • Store in Information registers.
  • Store in separate module, where this diagnostic is disabled (not recommended).
  • Store in Catalog, Exchange plan node and etc.

Examples

Incorrect: 

NetworkAddress = "192.168.0.1";

Correct: 

NetworkAddress = MyModuleReUse.ServerNetworkAddress();
