NAME

       ipv6loganon - HTTP server log file anonymizer

SYNOPSIS

       ipv6loganon [ -d value ] [ -V ] [ -n ] [ -c value ] [ --mask-ipv4 bits ] [ --no-mask-iid ] [ --anonymize-standard ]

DESCRIPTION

       ipv6loganon is a HTTP server log file anonymizer

       It expects a log line on stdin with an IPv4/IPv6 address as first token.

       This token would be anonymized according to given/default options.

       The anonymizer would keep as much information as possible for IPv6 address types.

       Client-side IID would be anonymized by

	      o EUI-48 based: serial number would be zero'ed, keeping OID

	      o EUI-64 based: serial number would be zero'ed, keeping OID

	      o ISATAP: client IPv4 address would be anonymized by given IPv4 mask

	      o TEREDO: client IPv4 address would be anonymized by given IPv4 mask, client port would be zero'ed

	      o 6to4(Microsoft): client IPv4 address would be anonymized by given IPv4 mask

	      o local: whole IID would be zero'ed

       Client-side SLA would be anonymized by

	      o SLA would be zero'ed

       Prefix would be anonymized by

	      o 6to4: client IPv4 address would be anonymized by given IPv4 mask

       Compat/Mapped IPv4 addresses would be anonymized by

	      o IPv4 address would be anonymized by given IPv4 mask

       Afterwards, the modified address and the trailing line would be printed to stdout.

OPTIONS

   GENERAL
       -d, --debug <debug value>
	      debug value (bitwise like)

       -V, --verbose
	      be verbose

       -n, --nocache
	      disable caching

       -c, --cachelimit
	      set cache limit (default: 20, maximum: 200)

   OUTPUT ANONYMIZATION
       --mask-ipv4 <bits>
	      mask all IPv4 addresses [0-32], default 8 even if occurs in IPv6-IID

       --no-mask-iid
	      do not mask non-IPv4 based IPv6-IID

       --anonymize-standard
	      preset for standard anonymization

       Default settings: mask-ipv4=8 mask-iid
