Dear All, A group of people in Turkey contacted us for BGP announcement of our 44.176.x.x/16 network. At first glance I ddn't want to interfere with non-amateur groups for our 44.176 IP block announcements. The group is Turkish volunteers for the PeeringDB (details can be found on their web page https://www.peeringdb.com/ https://ixp.ofis.link/peers.html) . As I checked other announcements of PeeringDB for 44.x.x.x network I saw that there are some other participants sharing their routing information with peeringDB. Samples 44.x.x.x network annoucements on peeringBD are as follows; https://bgp.he.net/AS396503#_prefixes ( 44.190.7.0/24 and 44.135.116.0/22 ) https://bgp.he.net/AS23738#_prefixes ( 44.24.193.0/24 44.127.44.0/22 44.127.45.0/24 44.127.46.0/24 44.127.47.0/24) https://bgp.he.net/AS207036#_prefixes ( 44.164.64.0/22 ) https://bgp.he.net/AS204778#_prefixes ( 44.38.10.0/24 ) My question is : Can I share the 44.176.x.x/16 network announcement with this group of people (the users on my side are all hamradio licensed amateurs, but the announcing will be done bye a non-hamradio person. Thanks Baris DINC TA7W

To give everyone else some more background, ixp.ofis is one of a new crop of what you might call "vanity Internet exchanges." Real Internet Exchanges are local peering points where multiple networks can exchange traffic to improve their connectivity vs only reaching other networks through your upstream Internet Service Provider (i.e. bypassing the up, over, and down hops through both network's transit providers). Some network operators think that it is "cool" to be on an IXP and have more direct peers, so they create these virtual GRE tunnel based IXPs as a way to juice their numbers and play with BGP regardless of it generally hurting the performance of their routing to any other participating networks. That being said, in general, if anyone unsolicited offers to announce your AMPRnet prefix over BGP from their network and you don't understand why you would want to do that or what it gains you, I recommend you decline the offer. Although possibly sincere, it's likely a vanity exercise on their part, and possible they're trying to steal access to some or all of your subnet for their own use. -- Kenneth Finnegan http://blog.thelifeofkenneth.com/ On Tue, Sep 4, 2018 at 6:25 AM, Barış DİNÇ <ta7w(a)antrak.org.tr> wrote:
