Hi Everyone, Just wanted to understand something about Bogons. As per RFC3871 - A "Bogon" (plural: "bogons") is a packet with an IP source address in an address block not yet allocated by IANA or the Regional Internet Registries (ARIN, RIPE, APNIC...) as well as all addresses reserved for private or special use by RFCs. See [RFC3330] and [RFC1918]. Q - Generally, Private or Reserved ASNs are considered as Bogon ASN but what about unallocated ASNs? Q - Is there any RFC (or even draft) which classify unallocated ASNs as Bogon as well? Additionally, Geoff Huston [1] explained all the possible classifications of "Bogon" in his blog post back in 2004 --> "Sometimes a bogon is just a case of keystroke error by a network operator, and the consequent bogons are entirely inadvertent, and other times it may be a disagreement between an end user and a registration authority" Q - In the above scenario when an RIR deregister a resource (IPv4/v6 or ASN) due to any disagreement (sometimes deregistration happens because of non-payment and can be resolved in a few days/weeks). How long should a service provider wait to mark them as bogon and stop advertising or accepting it? [1] - http://www.potaroo.net/ispcol/2004-04/2004-04-isp.htm
