About Reseed hosts
Reseed hosts are needed to for bootstrapping, that is, providing the initial set of I2P nodes for your I2P node to talk to. Depending on the status of your node it may need to bootstrap every now and then if many of the nodes it knows of aren't contactable.
Reseeding is done over an encrypted connection and all of the bootstrap information is signed by the reseed host you connect to, making it impossible for an unauthenticated source to provide you with false information.
Running a Reseed host
The more reseed hosts that are run, the more resilient the I2P network becomes, and the harder it is to prevent users of I2P from connecting to the network.There have also been cases where the reseed hosts we had, have been under heavy load due to botnet activities.
If you are running a reseed server, We would like to thank you for helping to make the I2P network stronger and more resilient than ever.
