  | I thought that some web servers do IP address checking.

For the kind of address changing that is being discussed here, they cannot
really now (one special case excepted) - NAT pretty much guarantees that
the local part of most users' addresses are unpredictable, and not stable
over time (that is kind of what v6 temporary addresses seek to replicate).

The exception is for web servers that are providing service only to
local users - and even those generally just check the prefix (though of
course anything is possible).
