刚才试着用update_hosts.py更新了一次，发现有不少用于DNS污染的错误的IP没有被过滤出来。

I couldn't find OpenThread's configurations description in https://openthread.io/reference. I think it helpful to have a centered place to introduce all OpenThread configuration and usage.

Describe the solution you'd like
Add a generated configurations page.

currently "option forwardfor" cant't be unset, so there is no way to enable it in the default section and disable it in a particular frontend

We should take a look at https://github.com/pkg/profile instead of using runtime/pprof for profiling.

Advantage: We could do memory profiles! The runtime only supports dumping the heap iirc, but this does actual profiles.

The navigation bar can occlude content, if the window is too narrow (here: half screen = 800 px), "add host" is covered then, see screenshot.

If you look at a cisco acl list, it is common to have an acl like:
rule 5 permit ip source 1.2.3.4 0.0.0.0
or in some cases:
rule 5 permit ip source 1.2.3.4 0

here both 0.0.0.0 and 0 are cisco acl bitmask, indicating a net mask of 32 bit length
but if I simply concatenate them with ip address, IPNetwork class will treat them as normal netmask and get the wrong result:

IPNetwork('1.2.3.4/0.0.

the script coulnd get all the ip addresses of the server interfaces when running xen dom0.
ifconfig does not show aliases for the bridge interface xenbr0 so server blocks his own ip-s.

i changed the line

SERVER_IP_LIST=ifconfig | grep "inet " | awk '{print $2}' | sed "s/addr://g" | xargs | sed -e 's/ /|/g'

to
SERVER_IP_LIST=`( hostname -I ; echo 127.0.0.1 ) | cat | sed ':a;N;$!ba;s/\n/ /g'

I've already retrieved some WHOIS records and stashed them in a file. Now I want to parse them (without retrieving them again).

Is there a way to access the WHOIS parser via the ipwhois API?

The code has a high number of nested blocks. This compromises both the readability of the code and the effectiveness of the dynamic analysis tools (as likely the compiler). This is the result of pushing for a single exit in methods (which is likely an academic heritage). Relaxing on that front would allow to more linear and readab

In order to simplify contribution process, code style guidelines should be explicitly mentioned for the project.

This command should ask for confirmation before applying the update and probably warn if the server is not in the same country anymore.

This should be easy to do for any newcomer who wants to contribute.
