Is RFC 1393 implemented by real routers in practice?
Are there any tools that generate traceroutes using it?
The new ICMP message type as defined in this RFC actually was added to the ICMP standard - though it's currently listed as Historic in RFC 6918:
2.6. Traceroute (Type 30)
This message type is specified in [RFC1393] and was meant to provide
an alternative means to discover the path to a destination system.
This message type has never been widely deployed. The status of
[RFC1393] has been changed to Historic by [RFC6814], and the
corresponding option this message type relies on (Traceroute, Type
82) has been formally obsoleted by [RFC6814].
And mentioned in RFC 6814 where it's formally deprecated:
The Traceroute option is defined in [RFC1393]. The Traceroute option
is defined as Experimental; it was never widely deployed on the
I very much doubt there would be any current tools that would support this kind of functionality.
Quoting from RFC6814 which obsoletes RFC1393
The Traceroute option is defined in [RFC1393]. The Traceroute option is defined as Experimental; it was never widely deployed on the public Internet.
So yes there should have been implementations for this (some one even implemented IP over avian carriers) but I've never seen one.
