history
Project history and usage
grepip is a standalone helper shipped from the IPinfo CLI repository for extracting and filtering IPv4 and IPv6 addresses with a grep-like interface. It is much thinner historically than GNU grep or grc, but official repository materials document its role inside IPinfo's family of small IP-address CLIs.
Project history
The IPinfo CLI README describes grepip alongside sibling standalone binaries such as grepdomain, matchip, prips, cidr2range, cidr2ip, range2cidr, range2ip, splitcidr, randip, and mmdb. The grepip source exposes flags for only matching IPs, including CIDRs and ranges, selecting IPv4 or IPv6, disabling color, recursing through directories, and excluding reserved or bogon IPs.
The GitHub release feed records grepip-specific releases beginning with grepip-1.0.0 on 2021-03-31 and continuing through the 1.2.x series. The grepip changelog records later additions for CIDR and range output flags and fixes for reserved/bogon edge cases.
Adoption history
grepip's adoption path is tied to the broader IPinfo CLI rather than to a standalone ecosystem. Homebrew packages it as its own formula, while the upstream README presents it as one of the extra binaries built from the IPinfo CLI repository.
How it is used
grepip scans standard input, files, or directories for IP-like text and prints matching lines or only the matching address tokens. Users can restrict matches to IPv4 or IPv6, include CIDR/range strings, disable color, and exclude reserved or bogon addresses.
Why package nerds care
grepip is useful to package-minded shell users because it separates IP extraction from IPinfo API lookup. That makes it a lightweight pipeline component for logs, pasted text, and files where ordinary grep patterns would be easy to get subtly wrong.
Its significance is mostly practical rather than historical: it packages a common IP-address parsing task into a tiny binary with familiar grep-flavored options.
Timeline
- 2021: grepip-1.0.0 published in the official GitHub release feed.
- 2021: grepip 1.1.0 and 1.2.0 followed in the same repository release feed.
- 2023: grepip-1.2.2 release metadata appeared, and the changelog records bogon edge-case fixes.
- Undated in changelog: grepip 1.2.3 added CIDR and range inclusion/output flags.
