Package Downloads
IPAddressRange.Signed
[Superseded] This package became only metadata package for installing "IPAddressRange" NuGet package, because "IPAddressRange" NuGet package became strong-named assembly. Please consider to installing "IPAddress" NuGet package directly instead of this package. ---------------------------- This library allows you to parse range of IP address string such as "192.168.0.0/24" and "192.168.0.0/255.255.255.0" and "192.168.0.0-192.168.0.255", and can contains check. This library supports both IPv4 and IPv6.
WhoisClient.NET
This library is a WHOIS protocol client used to search owner information by IP address or domain name. This library determines the WHOIS server automatically and queries the referral server recursively. The response of the whois query contains strongly typed values, and the raw output.
ZNetCS.AspNetCore.IPFiltering
A middleware that allows whitelist or blacklist incomming requests based on IP address. It can be configured using single IP address or ranges. It supports single IP, IP range IPv4 and IPv6. There is also possible to ignore specific paths from IP filtering.
IQX.RoleManager.Abstractions
Package Description
WhoisParsers
This allows you to: 1) Download and parse Whois records from bulk whois database dumps of IANA organizations (ARIN, AFRINIC, APNIC, LACNIC, RIPE ) and 2) Crawl and parse RWhois records from RFC 2167 ARIN Referral Whois Servers. It also provides utilities to increment IP addresses and to output Whois databases in TSV format.
