it is somewhat weired, because
wget http://[2a00:1a68:3:1::c5a5:8590]/
isn't blocked and the following are
all blocked as they should:
wget http://[2a00:1a68:3::c5a5:8590]/
wget http://[2a00:1a68:3:1::c5a:8590]/
wget http://[2a00:1a68:3:1::c5a5:859]/
wget http://[2a00:1a68:2:1::c5a5:8590]/

here this part in access.log

here the ACL

acl block_domains_iphost dstdom_regex "/etc/squid/iphost-acl.squid"
deny_info ERR_DOMAIN_IPHOST_BLOCKED block_domains_iphost
http_access deny block_domains_iphost

and iphost-acl.squid has the following content:

^[12]?[0-9]{1,2}\.[12]?[0-9]{1,2}\.[12]?[0-9]{1,2}\.[12]?[0-9]{1,2}$
^\[([0-9a-f]{0,4})(:|[0-9a-f]{0,4}){1,7}\]$
^\[::1\]$
^\[.*\]$
^([0-9a-f]{0,4})(:|[0-9a-f]{0,4}){1,7}$
^::1$
^.*$

some part above I have this in squid.conf

acl allow_domains dstdom_regex "/etc/squid/domain_regex-acl.squid"
http_access allow allow_domains

and domain_regex-acl.squid has the following content:

...
\.mathemainzel\.info$
...

what is this mystic, that
wget http://[2a00:1a68:3:1::c5a5:8590]/
isn't blocked, even it should ...

by the way  wget http://81.19.145.52/ is blocked as you see in the log

parentproxy.local - - [13/May/2016:10:12:53 +0200] "GET
http://81.19.145.52/ HTTP/1.0" 403 1550 "-" "Wget/1.12 (li
nux-gnu)" TCP_DENIED:HIER_NONE

just as an experiment, if I remove this one entry of domain_regex-acl.squid
then
wget http://[2a00:1a68:3:1::c5a5:8590]/
is blocked, why not with this entry?

Thanks and greetings from Austria,
Walter
