# Network Requirements Most Hedge apps use and connect to [LimeLM](https://wyday.com) ([wyday.com](https://wyday.com)) for license management, which also serves as the backbone of the [Hedge License Manager](/general/licenses/the-license-manager.md). When something unexpected happens, we use [Sentry](https://sentry.io/) for anonymized crash reporting. You'll be given the option to `Send` your report, we don't assume you will. When you contact support via an in-app form, we bundle the relevant logs for investigative and diagnostic purposes. These are delivered to our team by Google's mail servers.\ \ If you have a firewall in place, to activate your license and use other services around our apps, make sure to allow these domains to be accessed through port 443: * \*.wyday.com * \*.sentry.io * \*.hedge.video * \*.hedge.co If you can't do wildcards in your firewall, specify... * account.hedge.video * updates.hedge.video * connect.hedge.video and... * account.hedge.co * updates.hedge.co * connect.hedge.co IPs change all the time, so we can't specify those. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
