AdguardTeam/HostlistsRegistry#463

[Alex-302]

It is related to #1224 and should be handled by HostlistCompiler

@Alex-302
But can we exclude these rules temporarily until that task is completed?

[Alex-302]

Better use regexps.
I created few regexps for private IP ranges:
https://regex101.com/r/eW4OBB/1
https://regex101.com/r/kGYkDI/1

! 10.0.0.0 – 10.255.255.255
(?:^\|\|?|^)(10\.[\d\.*]+)\|{0,1}
! 127.0.0.0 – 127.255.255.255
(?:^\|\|?|^)(127\.[\d\.*]+)\|{0,1}
! 172.16.0.0 – 172.31.255.255
(?:^\|\|?|^)(172\.(?:1[6-9]|2[0-9]|3[0-1])\.[\d\.*]+)\|{0,1}
! 192.168.0.0 – 192.168.255.255
(?:^\|\|?|^)(192\.168\.[\d\.*]+)\|{0,1}

Note - in exclusions.txt expressions must be wrapped - /regexp/

You can add test rules and run local build to check result.

@AdamWr @piquark6046 Please also take a look, maybe regexps can be improved.

Is the above case included?

Is the above case included?

What is it?) Just invalid IP?

[AdamWr]

If I'm not wrong, rule like this:

||10.32.17.182espn.hb.tt.omtrdc.net^

will be also excluded by this regex, or not?

If so, maybe something like this:

(?:^\|\|?|^)(10\.[\d\.*\^\|]+)(?:\|\^){0,1}$

can be used?

{0,1} can be replaced with ?.

[Alex-302]

@piquark6046 replaced. In general ok?

[piquark6046]

#1646 (comment)
I think so.
