Thanks for reporting. Fixed in https://git.cloudron.io/platform/box/-/commit/5107cd28c4a0b8b362e9ee5da7151a9271db9fa3 . It won't collapse anymore and you can select it.
The link to http://www.barracudanetworks.com/reputation/?pr=1&ip= ... itself is broken, gets forwarded to https://www.barracuda.com/ which results in a 404. Working link is https://www.barracudacentral.org/lookups but I didn't manage to add the IP as parameter
This is actually the raw TXT record that is in their DNS. It would not be safe to render it as a link, since it is random external data. But also their DNS simply has raw links like above which are i guess broken. For example:
# host -t TXT 70.188.231.171.b.barracudacentral.org 127.0.0.150
Using domain server:
Name: 127.0.0.150
Address: 127.0.0.150#53
Aliases:
70.188.231.171.b.barracudacentral.org descriptive text "http://www.barracudanetworks.com/reputation/?pr=1&ip=171.231.188.70"
