Perform IP Address in CIDR Lookups with PostgreSQL and ip4r

Description

PostgreSQL has built-in support for IP address and CIDR types but the ip4r https://github.com/RhodiumToad/ip4r extension is much faster. Tools are provided to create CIDR lookup and IP address source tables and perform IP address in CIDR queries. Documentation on how to setup macOS with PostgreSQL and ip4r is also provided.

What’s Inside The Tin

The following functions are implemented:

• create_cidr_lookup_table: Creates a CIDR lookup table
• create_ip_source_table: Creates a IP address table
• find_ips_in_cidrs: Finds IPs in CIDR blocks
• macos_postgresql_setup_with_ip4r: Setting up macOS PostgreSQL 12 with ip4r extension

Installation

install.packages("pgcidr", repos = c("https://cinc.rud.is", "https://cloud.r-project.org/"))
# or
remotes::install_git("https://git.rud.is/hrbrmstr/pgcidr.git")
# or
remotes::install_git("https://git.sr.ht/~hrbrmstr/pgcidr")
# or
remotes::install_gitlab("hrbrmstr/pgcidr")
# or
remotes::install_bitbucket("hrbrmstr/pgcidr")
# or
remotes::install_github("hrbrmstr/pgcidr")

NOTE: To use the ‘remotes’ install options you will need to have the {remotes} package installed.

Usage

library(pgcidr)

# current version
packageVersion("pgcidr")
## [1] '0.1.0'

DBI::dbConnect(
  odbc::odbc(),
  driver = "/usr/local/lib/psqlodbca.so",
  Database = "working",
  Host = "localhost"
) -> con

create_cidr_lookup_table(
  pgcon = con,
  tbl_name = "amazon_cidrs",
  drop = TRUE,
  xdf = system.file("extdat", "amzn-cidrs.csv", package = "pgcidr"),
)

create_ip_source_table(
  pgcon = con,
  tbl_name = "weblog",
  drop = TRUE,
  xdf = system.file("extdat", "weblog.csv", package = "pgcidr")
)

find_ips_in_cidrs(
  con, "weblog", "amazon_cidrs"
)
