hi,

page 4 of the RFC 1788  says

"On receipt of an ICMP error message, the implementations MAY attempt to resolve the Domain Name using the IN-ADDR method."

i want to know what the term "ICMP error message"  refers to 

is it the Domain Name Request message received by the destination machine?

	if so would n't the machine have its own Domain Name? should it 
            find its Domain Name by IN-ADDR method.

else is it a ICMP error message received by the source which had sent a 
Domain Name Request?

	if so isnt this violating the general rule that no ICMP error for an ICMP?

please help me out. 

my mail id is [email-masked]

thanx a lot

with regards
