I-Invisible Internet Project (I2P) isendlalelo senethiwekhi esingaziwa (esisetshenziswa njengenethiwekhi exubile) esivumela ukuvikeleka kokuvimbela, ukuxhumana kontanga kuya kontanga. Ukuxhumana okungaziwa kufinyelelwa ngokubhala ngemfihlo ithrafikhi yomsebenzisi (ngokusebenzisa ukubethela ngasemaphethelweni), futhi kuyithumele ngenethiwekhi eqhutshwa amavolontiya cishe amakhompyutha angu-55,000 asakazwa emhlabeni jikelele. Uma kubhekwa inani eliphezulu lezindlela ezingaba khona ithrafikhi engadlula, inkampani yangaphandle ebuka uxhumano olugcwele mancane amathuba okuba. Isofthiwe esebenzisa lesi sendlalelo ibizwa ngokuthi “irutha ye-I2P”, futhi ikhompuyutha esebenzisa i-I2P ibizwa ngokuthi “i-I2P node”. I-I2P imahhala futhi inomthombo ovulekile, futhi ishicilelwa ngaphansi kwamalayisensi amaningi.
