# Which Problems Are Solved
System administrators can block hosts and IPs for HTTP calls in actions.
Using DNS, blocked IPs could be bypassed.
# How the Problems Are Solved
- Hosts are resolved (DNS lookup) to check whether their corresponding
IP is blocked.
# Additional Changes
- Added complete lookup ip address range and "unspecified" address to
the default `DenyList`
