Forget about IPs in Vagrant - Automated DNS for your VMs This Vagrant plugin spins up a lightweight DNS server and makes it visible to your guests and your host, so that you can easily access all your machines without having to fiddle with IP addresses. DNS records are automatically added and removed as machines are brought up and down, and you can configure static entries to be returned from the server as well. See the README for more documentation.
A Vagrant plugin that allows you to set up route53 records for instances created using vagrant-aws provider. A temporary fork until https://github.com/nasskach/vagrant-aws-dns/pull/9 is merged.
Keep a dynamic IP up to date without the use of DNS. Either sync manually or automatically to a known location.

Antispam helps prevent spam in your Rails applications by checking against DNS blacklists and spam-prevention databases. It has two core features: (1) IP-based spam detection using Project Honey Pot to block known spammers automatically, and (2) content-based spam detection using Defendium’s machine learning API, which is free for up to 1,000 checks per day. Blacklist lookups are cached for 24 hours to minimize performance impact. The gem integrates seamlessly with Rails, allowing you to block spam at the request level and redirect flagged users to a captcha page.
A daemon, running in background on a Linux router or firewall, monitoring the state of multiple internet uplinks and changing the routing accordingly. LAN/DMZ internet traffic (outgoing connections) is load balanced between the uplinks using Linux multipath routing. The daemon monitors the state of the uplinks by routinely pinging well known IP addresses (Google public DNS servers, etc.) through each outgoing interface: once an uplink goes down, it is excluded from the multipath routing, when it comes back up, it is included again. An uplink may be assigned to a priority group: lower priority uplinks will only be used if all higher priority ones are down. That's useful to only use pay-per-traffic uplinks if no regular uplink is working. All of the routing changes are notified to the administrator by email. Fault Tolerant Router is well tested and has been used in production for several years, in several sites. See https://github.com/drsound/fault_tolerant_router for full documentation.
