Detects IPv4 and IPv6 addresses

PCRE (PHP <7.3)
This is loosely based on some other examples, but goes a bit further in terms of what it will and won't match. In particular, it matches IPv6 addresses like ff02::, ff02:1000::, and (the syntactically valid but improbable) ::0001:0002

Description

Finds table names in table list and subqueries. Table names are in group #1 of all matches One note. In case of table list (like SELECT * FROM table1, table2, etc) group#1 will contain all tables string (like "table1, table2, etc"). In case of subquery in a table list group#1 may contain also other symbols besides table names and commas (most likely - "(" ). So it's necessary to do additional handing like splitting the string.
